| I. \[F-C{{H}_{2}}-COOH\] |
| II.\[Cl-C{{H}_{2}}-COOH\] |
| III. \[Br-C{{H}_{2}}-COOH\] |
A) \[I>II>III\]
B) \[III>II>I\]
C) \[II>III>I\]
D) \[II>I>III\]
Correct Answer: A
Solution :
On increasing\[-I\]effect of R group, the acidic strength of carboxylic acid increases. Hence increasing order of acidic strength is \[F-C{{H}_{2}}COOH>Cl-C{{H}_{2}}COOH>Br\]\[-C{{H}_{2}}COOH\] \[I>II>III\]
