A) +M effect
B) \[-I\]effect
C) \[+I\]effect
D) -M effect
Correct Answer: C
Solution :
\[\underset{'+I'\,(acetic\text{ }acid)}{\mathop{{{H}_{3}}C\to -\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-O-H}}\,\] \[\underset{(formic\text{ }acid)}{\mathop{H-\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-O-H}}\,\] In acetic acid, methyl group release electron due to \[+I\] effect which decreases its acidic character whereas, formic acid does not contain any such type of group. Hence, formic acid is stronger acid than acetic acid.You need to login to perform this action.
