MCQ
Which of the following statements is incorrect
  • A
    ${C_2}{H_5}Br$ reacts with alco. $KOH$ to form ${C_2}{H_5}OH$
  • B
    ${C_2}{H_5}Br$ when treated with metallic sodium gives ethane
  • C
    ${C_2}{H_5}Br$ when treated with sodium ethoxide forms diethyl ether
  • ✓
    Both $(a)$ and $(b)$
✓

Answer

Correct option: D.
Both $(a)$ and $(b)$
d
(d) ${C_2}{H_5}Br + alc{\rm{.}}K{\rm{OH}} \to {C_2}{H_4} + {H_2}O + KBr$

${C_2}{H_5}\,\boxed{Br + 2Na + Br} - {C_2}{H_5} \to \mathop {{C_2}{H_5} - {C_2}{H_5}}\limits_{{\text{Butane}}}  + 2NaBr$
