Text Solution

Verified by Experts

The correct Answer is:
C
`underset("Acetic Acid")(CH_(3)-overset(O)overset(||)C-OH) underset(-SO_(2),-HCl)overset(SOCl_(2))tounderset("Acetyl chloride")(CH_(3)-overset(O)overset(||)C-Cl)underset(-CH_(3)Cl,-N_(2))overset(2CH_(2)N_(2))to underset("Diazomethyl ketone")(CH_(3)-overset(O)overset(||)C-overset(H)overset(|)C=N_(2)) underset(2.H_(2)O)overset(1.Ag_(2)O,-N_(2))to underset("Propionic acid")(CH_(3)-CH_(2)-COOH)`
This method is used for conversion of a carboxylic acid to its next higher homologue.
