_____amide
_____ether
_____carboxylic acid
_____phenol
_____alcohol
_____ester

Answer 1

Concept and reason

Functional groups mainly determine the nature of the compound.

First calculate the double bond equivalence using the molecular formula and then identify the class of given compounds to which it belongs to.

Fundamentals

Double bond equivalence is calculated using the following formula:

Here, C is the number of carbon atoms, H is the number of hydrogen atoms, X is the number of halogen atoms and N is the number of nitrogen atoms.

The general formula and the functional groups are tabulated as follows:

The DBE is calculated as follows:

The general representation of the given class of compounds is as follows:
