Arrange the following compounds in an increasing order of their proper

1.	Arrange the following compounds in an increasing order of their property as indicated :(i) Benzoic acid, 3,4-dinitrobenzoic acid, 4-methoxybenzoic acid (acid strength).(ii) CH3CH2CH(Br)COOH, CH3CH(Br)CH2COOH, (CH3)2CHCOOH (acid strength).
Answer» (i) The overall acid strength increases in the order. 4-methoxybenzoic acid < benzoic acid < 3,4-dinitrobenzoic acid. (ii) We know that +I-effect decreases while –I-effect increases the acid strength of carboxylic acids. The overall acid strength increases in the order. (CH₃)₂CHCOOH < CH₃CH(Br)CH₂COOH < CH₃CH₂CH(Br)COOH

Arrange the following compounds in an increasing order of their property as indicated :(i) Benzoic acid, 3,4-dinitrobenzoic acid, 4-methoxybenzoic acid (acid strength).(ii) CH3CH2CH(Br)COOH, CH3CH(Br)CH2COOH, (CH3)2CHCOOH (acid strength).

Answer»

(i) The overall acid strength increases in the order.

4-methoxybenzoic acid < benzoic acid < 3,4-dinitrobenzoic acid.

(ii) We know that +I-effect decreases while –I-effect increases the acid strength of carboxylic acids. The overall acid strength increases in the order. (CH₃)₂CHCOOH < CH₃CH(Br)CH₂COOH < CH₃CH₂CH(Br)COOH
