Equilibrium Question 899

Question: Choose the correct order of strength of following acids.

(i) $ CH_3CH_2CH_2COOH $

(ii) $ ~CH_3CH_2CH(Br)COOH $

(iii) $ CH_3CH(Br)CH_2COOH $

(IV) $ {{(CH_3)}_2}CHCOOH $

Options:

A) I < II < III < IV

B) IV < I < III < II

C) IV < III < I < II

D) II < I < III < IV

Show Answer

Answer:

Correct Answer: B

Solution:

AlkyI group with + 1 effect decreases the acidic strength whereas with - 1 effect increases the acidic strength - 1 effect decreases with distance.

$ \therefore $ Increasing order of acidic strength is $ {{(CH_3)}_2}CHCOOH<CH_3CH_2CH_2COOH $ $ <CH_3CH(Br)CH_2COOH< $ $ CH_3CH_2CH(Br)COOH $
