Vedclass · Answer

(A) The reaction of an alkene with a singlet carbene $(:CH_2)$ is a stereospecific syn-addition reaction.Since the starting material is cis-but$-2-$ene,the addition of the singlet carbene occurs from the same face of the double bond,preserving the cis-stereochemistry of the methyl groups.Therefore,the major product formed is cis$-1,2-$dimethylcyclopropane.

The major product formed in the following reaction is:
