14 Jun 2016 Many functional groups incorporated into PEG can be easily quantified by 1H NMR Synthesis of BocNH‐PEG‐Triazole(CO2Et)2 (2b).
By Many organic chemistry molecules contain groups of atoms known as functional groups. Here is a list of common organic functional groups. Functional groups are collections of atoms in organic chemistry molecules that contribute to the chemic How well do you know your common organic functional groups?

A protective group (also referred to as "protecting group") is a reversably formed derivative of an existing functional group in a molecule. The protective group is temporarily attached to decrease reactivity so that the protected functional group does not react under synthetic conditions to which the molecule is subjected in one or more subsequent steps.

Carboxyl groups have the formula -C(=O)OH, usually written as -COOH or CO 2 H. Carboxylic acids are a class of molecules which are characterized by the presence of one carboxyl group.

Add to Wishlist. The most important app for organic chemistry students includes 80 functional groups, the classes of organic compounds (aldehyde, ethers, esters, etc.) and natural products (nucleic acids, carbohydrates, lipids, etc.).
Functional Groups. Bromine reacts with 2-butene to form 2,3-dibromobutane. It also reacts with 3-methyl-2-pentene to form 2,3-dibromopentane. Instead of trying to memorize both equations, we can build a general rule that bromine reacts with compounds that contain a C=C double bond to give the product expected from addition across the double bond. This approach
Ketonesand aldehydesare two closely related carbonyl-based functional groups that react in very similar ways.

Favorite Answer The carbon atom is single-bonded to one oxygen atom, double-bonded to the other. The single-bonded oxygen atom is attached to Et. Et stands for ethyl.
