WBJEE · Chemistry · Haloalkanes and Haloarenes
Increasing order of the nucleophilic substitution of following compounds is
- A \(I \lt I I I \lt I I \lt I V\)
- B \(I I \lt I \lt I I I \lt I V\)
- C \(I I \lt I I I \lt I \lt I V\)
- D \(I V \lt I I I \lt I I \lt I\)
Answer & Solution
Correct Answer
(B) \(I I \lt I \lt I I I \lt I V\)
Step-by-step Solution
Detailed explanation
\(I I \lt I \lt I I I \lt I V\) Electron withdrawing group decreases the electrondensity and favours nucleophilic substitution.
