Formic acid reacts with $\mathrm{PCl}_5$ to form

  • A
    methyl chloride
  • B
    acetyl chloride
  • C
    formyl chloride
  • Correct answer
    D
    carbon monoxide and hydrogen chloride

Solution

Formic acid reacts with \(\mathrm{PCl}_5\) to give carbon monoxide and hydrogen chloride. \(\mathrm{HCOOH}+\mathrm{PCl}_5 \rightarrow \underset{\text { unstable }}{[\mathrm{HCOCl}]} \rightarrow \mathrm{CO}+\mathrm{HCl}\)

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