Q. The compound A on treatment with Na gives B, and with $PCl_5$ gives C. B and C react together to give diethyl ether. A, B and C are in the order
A) $C_2H_5Cl$, $C_2H_6$, $C_2H_5OH$
B) $C_2H_5OH$, $C_2H_5Cl$, $C_2H_5ONa$
C) $C_2H_5OH$, $C_2H_6$, $C_2H_5Cl$
D) $C_2H_5OH$, $C_2H_5ONa$, $C_2H_5Cl$
Explanation
[Solution] Ethanol + Na gives sodium ethoxide; ethanol + $PCl_5$ gives ethyl chloride; Williamson synthesis gives diethyl ether. Answer (4).
