Question
Which compound in a) and b) is more acidic? Also which effect contributes to the stabilization of the conjugate base?
The image contains chemical structures arranged in two parts labeled (a) and (b). ### (a) Chemical Structures: 1. **Left Structure:** - A six-membered carbon ring (cyclohexane ring). - A fluorine atom (F) is attached to one of the carbon atoms. - An amino group (NH₂) is attached to a neighboring carbon atom. 2. **Right Structure:** - Another six-membered carbon ring (cyclohexane ring). - A chlorine atom (Cl) is attached to one of the carbon atoms. - An amino group (NH₂) is attached to a neighboring carbon atom. ### (b) Chemical Structures: 1. **Left Structure:** - A five-carbon chain with two ketone groups (C=O) on the second and fourth carbons. - Methyl groups (CH₃) are attached to the first and fifth carbons. 2. **Right Structure:** - A three-carbon chain with a ketone group (C=O) on the second carbon. - A methyl group (CH₃) is attached to the first carbon. These structures demonstrate variations in substituents on cyclohexane rings and different carbonyl-containing carbon chain molecules.

Expert Solution
Step 1 Theory

More stable the conjugate base of an acid, higher is the acidity of that acid.

Electron withdrawing atom/group stabilise the conjugate base.

Conjugation increases the stability of conjugate base.

Stability increases with increase in number of resonating structures.
