Which of the functional groups shown above is most likely to gain a proton and become positively charged? which of the functional groups shown above is most likely to gain a proton and become positively charged? the amino group is most likely to gain a proton. the carboxyl group is most likely to gain a proton. the hydroxyl group is most likely to gain a proton?

Respuesta :

Answer;

The amino group is most likely to gain a proton.

Explanation;

An amino group acts as a base and can pick up protons from the surrounding medium, becoming positively charged.

Amino acids have a two-carbon bond. One of the carbons is part of a group called the carboxyl group (COO-). A carboxyl group is made up of one carbon (C) and two oxygen (O) atoms. That carboxyl group has a negative charge, since it is a carboxylic acid (-COOH) that has lost its hydrogen (H) atom.

The second carbon is connected to the amino group. Amino means there is an NH2 group bonded to the carbon atom.
