Question

In Reimer Tiemann reaction dichlorocarbene acts as:

• A. nucleophile
• B. electrophile
• C. free radical
• D. all of these

Answer 1

The correct option is B electrophile

Reimer Tiemann reaction is an electrophilic substitution reaction.
The first step is :
$CHC{l}_3+O{H}^{-}\rightleftharpoons H_{2}O+C^{-}C{l}_3\to :CC{l}_2+C{l}^{-}$
Dichlorocarbene contains a sextet of electron and thus is a strong electrophile. Hence, the correct answer is option (b).
