• B.
• C.
• D.

Answer 1

Answer: (B)

(a) $C _{6} H _{5} COOC _{2} H _{5}+\left( CH _{3}\right)_{2} NH \rightarrow C _{6} H _{5} CON \left( CH _{3}\right)_{2}+ C _{2} H _{5} OH$
(b) $C _{6} H _{5} CONH _{2}+ CH _{3} MgI \rightarrow C _{6} H _{5} CONHMgI + CH _{4}$
(c) $C _{6} H _{5} COCl +\left( CH _{3}\right)_{2} NH \rightarrow C _{6} H _{5} CON \left( CH _{3}\right)_{2}+ HCl$
(d) $C _{6} H _{5} CO \cdot O \cdot COC _{6} H _{5}+\left( CH _{3}\right)_{2} NH \rightarrow C _{6} H _{5} CON \left( CH _{3}\right)_{2}+ C _{6} H _{5} COOH$
