Question

Predict the products of the following reactions.

Short answer

Cyclopentanone on treatment with hydroxylamine in acidic medium generates oxime. It is a condensation reaction and loss of water molecule is there. Oximes exists as thick liquids and are insoluble in water.

Oxime of cyclopentanone

Step-by-step solution

Explanation of part (a):

Cyclopentanone on treatment with hydroxylamine in acidic medium generates oxime. It is a condensation reaction and loss of water molecule is there. Oximes exists as thick liquids and are insoluble in water.

Oxime of cyclopentanone

Explanation of part (b):

The given reactant on treatment with hydrazine in acidic medium gives hydrazone as the product. This is a condensation reaction and loss of water molecule occurs as a result.

Hydrazone of 3,4-dihydronapthalen-1-one

Explanation of part (c):

Benzophenone on reaction with phenylhydrazone in acidic medium generates phenylhydrazine of benzophenone as the product. This reaction is condensation reaction and occurs with a loss of water molecule.

Phenylhydrazine of benzophenone

Explanation of part (d):

Cinnamaldehyde on reaction with semicarbazide in acidic medium leads to the generation of semicarbazone of cinnamaldehyde. It is a condensation reaction which occurs with a loss of water molecule.

Semicarbazone of cinnamaldehyde
