Choose the correct order of strength of following acids. |
(i) \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}COOH\] |
(ii) \[~C{{H}_{3}}C{{H}_{2}}CH(Br)COOH\] |
(iii) \[C{{H}_{3}}CH(Br)C{{H}_{2}}COOH\] |
(IV) \[{{(C{{H}_{3}})}_{2}}CHCOOH\] |
A) I < II < III < IV
B) IV < I < III < II
C) IV < III < I < II
D) II < I < III < IV
Correct Answer: B
Solution :
[b] 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 |
\[{{(C{{H}_{3}})}_{2}}CHCOOH<C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}COOH\] |
\[<C{{H}_{3}}CH(Br)C{{H}_{2}}COOH<\]\[C{{H}_{3}}C{{H}_{2}}CH(Br)COOH\] |
