A) \[HCOOH>C{{H}_{3}}COOH>{{H}_{2}}S>HCN\]
B) \[C{{H}_{3}}COOH>HCOOH>{{H}_{2}}S>HCN\]
C) \[{{H}_{2}}S>HCOOH>C{{H}_{3}}COOH>HCN\]
D) \[HCOOH>{{H}_{2}}S>C{{H}_{3}}COOH>HCN\]
Correct Answer: A
Solution :
[a] The greater the (negative value) of heat of neutralisation, the more is the strength of the acid. Hence, \[HCOOH>C{{H}_{3}}COOH>{{H}_{2}}S>HCN\]You need to login to perform this action.
