MCQ
The correct order of increasing intermolecular hydrogen bond strength is .... .
  • A
    $HCN < H _{2} O < NH _{3}$
  • B
    $HCN < CH _{4}< NH _{3}$
  • $CH _{4}< HCN < NH _{3}$
  • D
    $CH _{4}< NH _{3}< HCN$

Answer

Correct option: C.
$CH _{4}< HCN < NH _{3}$
c
Order of $H$-Bonding

$CH _{4}\,<\, HCN \,<\, NH _{3}$

$NCH \ldots NCH$

$H _{2} NH \ldots NH _{3}$
