The electrophile involved in the Reimer-Tiemann reaction isA. dichloromethyl cation, `overset(+)CHCl_(2)`B. formyl cation `overset(+)CHO`C. trichloromethyl anion, `overset(-)C Cl_(3)`D. dichloro carbene : `"CCl"_(2)`

Answer» Correct Answer - D
In Reimer-Tiemann reaction the electrophile involved is dichlorocarbene, `:"CCl"_(2).`
`CHCl_(3)+OH^(Theta)rarr underset("(Unstable)")(.^(Theta)"CCl"_(3))+H_(2)O`
`.^(Theta)"CCl"_(3)rarr underset("Dichlorocarbene")(":CCl"_(2))+Cl^(-)`
