Q78 / 180 · AIIMS 2009 · Chemistry

Assertion : $\mathrm{C}_2 \mathrm{H}_5 \mathrm{Br}$ reacts with alcoholic solution of $\mathrm{AgNO}_2$ to form nitroethane as the major product. Reason : $\mathrm{NO}_2^{-}$is an ambidient ion.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion
  • Correct answer
    B
    If both assertion and reason are true but reason is not the correct explanation of assertion
  • C
    If assertion is true but reason is false
  • D
    If both assertion and reason are false.

Solution

The lone pair electrons on $\mathrm{N}$ atom in $\mathrm{AgNO}_2$ attacks $\mathrm{C}_2 \mathrm{H}_5 \mathrm{Br}$ to form nitroethane as the major product.

Hence, the correct answer is option: 'B'.
