(b) Name the product obtained by the reaction of acetyl chloride with dimethylcadmium. (c) Explain the reaction between carboxylic acid and PCI5

Explanation

(a) Two molecules of aldehydes do not contain a-hydrogen atoms are reacted with strong solution of NaoH to produce alcohol and salt of carboxylic acid.

(b) Acetone (c ) when carboxylic acid reaction with PCI_(5) to form coressponding acid chloride.
` RCOOH+PCI_(5) TO RCOCI+POCI_(3)+HC`I
eg.` CH_(3) COOH+PCFI_(5) to underset(acetyl chride)CH_(3) COCI+POCI_(3)+HCI`
