Predict the product for the following reaction sequence. (CH102NH 49. P the major product for the following reaction scQuence. KOH CHCHExplanation / Answer
40: Answer: I
Step-1: Friedel crafts acylation:
When benzene reacts with benzoyl chloride under AlCl3, gives benzophenone.
Step-2: Clemmenson reduction:
Zinc amalgam reduces the ketone into an alkane. Here, Zinc amalgam reduces the benzophenone into diphenylmethane (I).
43: Answer-B
Step-1: Friedel crafts alkylation:
Benzene reacts with chloroethane under AlCl3 gives ethylbenzene.
Step-2: Halogenation:
Ethylbenzene reacts with chlorine molecule gives, 4-chloro-4-ethylbenzene.
Step-3: 4-chloro-4-ethylbenzene reacts with KMnO4 gives 4-chlorobenzoic acid.
Hence, condition B is the answer.
66: Answer- option A(I)
According to crossed Aldol reaction, gives option A is the answer.
48: Answer-II:
Step-1: PCC is a strong reducing agent. It reduces the alcohol into aldehyde.
Step-2: The obtained aldehyde reacts with dimethylamine gives option II as the product.
62: Answer- option C(III)
According to Aldol reaction, gives option C is the answer.
