Q. Friedel-Crafts reaction of one mole of carbonyl chloride $\left( COCl _{2}\right)$ with $2$ moles of benzene yields product ' $X$ '. The total number of $sp ^{2}$ hybridised C-atoms in product $X$ is_____.
Aldehydes Ketones and Carboxylic Acids
Solution:
Friedel-Crafts acylation reaction of carbonyl chloride (i.e., phosgene) with benzene produces benzophenone. In benzophenone, all the $C$-atoms including carbonyl'carbon are $sp ^{2}$ hybridised.
