Question

Name the functional group present in ${{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{COOH}$

Answer 1

Hint: Before we find out the functional group that is present in ${{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{COOH}$, we should be knowing what is the meaning of functional group. Functional groups are defined as one or more atoms of distinctive chemical properties no matter what they are attached to. The atoms that are present in the functional groups are linked to each other and to the rest of the molecules by covalent bonds.

Step by step answer:
The functional group that is present in ${{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{COOH}$ is carboxylic acid. A carboxylic acid is an organic compound that contains a carboxyl group that is attached to a R-group. The general formula of a carboxylic acid is $\text{R }-\text{ COOH}$. The R that is present in the general formula refers to the alkyl group. Carboxylic acid is found widely. Some of the important examples of carboxylic acids are amino acids and fatty acids.
Carboxylic acids are polar in nature. Because they are both hydrogen bond acceptors, which is the carbonyl C=O, and also the hydrogen bond donors, which is the hydroxyl OH, they also participate in the hydrogen bonding.
Carboxylic acids and their derivatives are used in the production of polymers, biopolymers, coatings, adhesives, and pharmaceutical drugs. They can also be used as solvents, food additives, antimicrobials, and flavourings.
The simplest of the carboxylic acid is the Formic Acid. The formula of the carboxylic acid is HCOOH.
Therefore, the functional group present in ${{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{COOH}$ is carboxylic acid.

Note: We should also know that carboxylic acids have higher boiling points of water. This is because of their greater surface areas and their tendency to form stabilised dimers through hydrogen bonds. For boiling to occur, either the dimer bonds must be broken or the entire arrangement must be vaporised, thus increasing the enthalpy of vaporization requirements significantly.
