Question

$C_6{H}_{5}OH+CHC{l}_3+NaOH\to Salicylaldehyde$. The electrophile involved in the above reaction is.

• A. dichloromethylcation $\stackrel{+}{C}HC{l}_2$
• B. dichlorocarbene $(:CC{l}_2)$
• C. trichloromethylanion $\left(\overline{C}C{l}_3\right)$
• D. formyl cation $\left(OH\right)\stackrel{+}{C}$

Answer 1

The correct option is B dichlorocarbene $(:CC{l}_2)$

$H_{2}O+CC{l}_3^{-}\to :CC{l}_2+C{l}^{-}$
Electrophile (dichlorocarbene)
