In some occasions, you will have to write an essay in the extremely short amount of time on the exam in college or high school. Also, you may be a little bit of a procrastinator, and find yourself in a situation when the paper is due tomorrow morning, and you have not even chosen the topic yet. Even though a last-minute essay cannot look as great as a work prepared successively and carefully within the whole time given, you still have a chance to submit a decent paper. The working process will require your full attention and a lot of effort, even if you are assigned a simple essay. However, if you learn the next few tips, the essay writing will seem significantly easier and feasible even when you are short on time.

Firstly, clean up your working space to get started. Make sure you have everything you need on the table, take a pen, a few sticky notes, your laptop, and read through the assignment requirements. In case no prompt is given, search for good essay topics, and pick a few uncommon and interesting ones you will be able to write about. Making a final choice, think which topic is the most relevant to your current studies and will not take too much to research.

Afterwards, look for the most trustworthy sources or the ones you are certainly allowed to use. If you are not sure, access the online library or any free services where you can look for the books and articles for your essay. Use sticky notes to write down the information and put them in front of you to see how much data has been gathered and if you need to continue researching. Reread these notes from time to time and cross out the info you do not find relevant anymore.

When you have the data you need to produce a quality work, it is crucial to think about the structure of the future paper. If you are not sure how to write an essay outline properly, check what your essay type is first. Each type is organized differently, so you need to look up the structure every time you are given an essay homework. You can also search for an example of the essay on your topic, and adhere to its outline. No matter what kind of essay you are going to write, it is important to start with a thesis statement. It should declare what problem you will review in the paper, and which facts or arguments you will use to do it professionally. As these arguments will be discussed in the main part of the essay, outline the body paragraphs and put down a few sentences with the rough description of each paragraph. Think of the way you will engage the reader in the introduction, and which thought will be conclusive for the paper. When the direction of the work is clear from the outline, use it to draft the first version of the essay.

If you are not used to model essay writing, do not worry - your draft should not necessarily look like a masterpiece. It is only the depiction of your thoughts, and as you will have them written down, it will be easier to create a good essay. There is no best way to write an essay, so trust the working methods you usually use. You may like taking short breaks once in a few minutes, or write everything in one sit - just make sure to keep the focus on writing and avoid the urge to call a friend or watch something online. Thus, you will finish the paper faster, and will not feel guilty for engaging in other activities afterwards.

Do not forget to go through the essay a few times after the completion. Everyone makes typos and mistakes by accident, but it is about you to find and fix them before your teacher does. If you need help with an essay editing, try asking a friend or a family member to read and analyze your work. Also, you can order editing services in case your paper needs to be perfectly polished so that you can submit an ideal essay and get an excellent grade.

As these steps are simple to follow, you will not have any problems coping with an essay on time. Try the whole procedure at least once, and you will not have to use any other tips preparing an essay paper during your studies!

Is optical rotation the same for enantiomers?

Each enantiomer of a stereoisomeric pair is optically active and has an equal but opposite-in-sign specific rotation.

What is the optical rotation of enantiomers?

Enantiomers will rotate the plane of polarisation in exactly equal amounts (same magnitude) but in opposite directions. If only one enantiomer is present a sample is considered to be optically pure. When a sample consists of a mixture of enantiomers, the effect of each enantiomer cancels out, molecule for molecule.

What is the optical rotation of R )- Carvone?

1. The specific rotation of (S)-carvone is (+)61°, measured ‘neat’ (pure liquid sample, no solvent). The optical rotation of a neat sample of a mixture of R and S carvone is measured at (-)23°.

What is the optical rotation of a racemic mixture of enantiomers?

A Racemic Mixture Is An Equal Mixture Of Two Enantiomers And Has A Specific Rotation of 0° (Optically Inactive)

Are enantiomers optically inactive?

Enantiomers have identical chemical and physical properties and are indistinguishable from each other except for the direction of rotation of the plane of polarized light. They are described as optically active.

Do diastereomers have same optical rotation?

Unlike enantiomers, diastereomers have different physical properties. They have different melting points, boiling points, densities, etc. While the optical rotations of enantiomers are equal and opposite, there is no a priori relationship between the optical rotations of diastereomers.

Why are enantiomers optically active?

Enantiomers by definition, is two molecules that are mirror image to each other and that are not superimposable. This tends to apply to chiral molecules. Chiral molecules rotate a plane-polarized light, and by definition a compound that rotates the plane of polarized light is said to be optically active .

What is the density of r (-) carvone?

0.96 g/cm3

Appearance Clear, colorless liquid
Density 0.96 g/cm3
Melting point 25.2 °C (77.4 °F; 298.3 K)
Boiling point 231 °C (448 °F; 504 K) (91 °C @ 5 mmHg)

What functional groups does carvone have?

Carvone contains a ketone and two alkene functional groups. One of the alkenes is conjugated with the ketone (called a conjugated enone); the other alkene is not conjugated.

What is difference between enantiomers and racemic mixture?

Enantiomers are stereoisomers which are nonsuperimposable, mirror images. A mixture of equal amounts of two stereoisomers of an optically active substance is called a racemic mixture or racemate.

Why do enantiomers rotate plane-polarized light?

This is because that for every molecule in the mixture that rotate the plane of polarization in one direction, there is an enantiomer molecule that rotate the plan of polarization in the opposite direction with the same angle, and the rotation get cancelled out.
