Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

sample resume for office managers - Ether is a class of organic compounds consisting of an oxygen atom that is chemically bonded to two alkyl groups or aryl groups. Ether, alcohol, and water have similar chemical structures. In alcohol, a single hydrogen atom of a water molecule is replaced by the alkyl functional group. General formula of ether is R-O-R, R-O-Ar or Ar-O-Ar. Physical and Chemical Properties of Ether: There is presence of net dipole in ether molecules. This is the reason behind polarity of C--O bonds. It has a much lower boiling point in comparison to alcohols. Dissolving capacity of ether is the same as alcohol. Ether can be named in two ways. One way is to identify the alkyl groups on either side of the oxygen atom in alphabetical order, followed by ‘ether’. For example, ethyl methyl ether is the ether that has an ethyl group and methyl group on either side of the oxygen atom. If two alkyl groups are the same, the ether is called di (alkyl) ether. research topics in thesis statement

What is the common name of the simplest ether? dimethyl ether. Which one of the following biochemical species contains a thioester bond that plays a key role in its function? Hydroboration-Oxidation is a two step pathway used to produce alcohols. The reaction proceeds in an Anti-Markovnikov manner, where the hydrogen (from BH 3 or BHR 2) attaches to the more substituted carbon and the boron attaches to the least substituted carbon in the alkene bouble bond. Furthermore, the borane acts as a lewis acid by accepting two electrons in its empty p orbital from an alkene. Ether is formed when an oxygen atom is connected to two alkyl or aryl groups.
