And Reason are true, and Reason is the correct explanation for Assertion.
The Reimer-Tiemann reaction is an example of electrophilic substitution, where an electrophile is introduced into an aromatic ring, resulting in the substitution of a hydrogen atom. The electrophile used in this reaction is not dichloromethylene itself, but rather a complex of it with hydroxide ions, which is formed in situ during the reaction. This complex acts as the electrophile and attacks the benzene ring, leading to the formation of a phenol derivative.
Dichloromethylene is indeed electron deficient, as it lacks a full octet of electrons and has a partial positive charge on the carbon atom. It is formed by the reaction of chloroform with a base, such as potassium hydroxide, which abstracts a proton from the chloroform molecule. This results in the formation of dichloromethylene and a chloride ion. The electron deficiency of dichloromethylene makes it a good electrophile, as it can react with electron-rich compounds such as aromatic rings.
Therefore, both Assertion and Reason are true, and Reason is the correct explanation for Assertion.

Yeah...option A is correct..because The reagent of Reimar Tiemann is CHCH3 + ALC KOH and heat...CCL4 AND H3O+ also.. but chloroform and alcoholic KOH reacts and form dichlorocarbene..it is Elctrophilic substitution reaction.
