MCQ
Length of the hydrogen bond range from $1.75 \mathring{\text{A}}$ to $ .........$
  • $2.5\mathring{\text{A}}$
  • B
    $2.75\mathring{\text{A}}$
  • C
    $2.6\mathring{\text{A}}$
  • D
    $3.2\mathring{\text{A}}$

Answer

Correct option: A.
$2.5\mathring{\text{A}}$
As $H-$ bond is a weak bond compared to other covalent bonds, its bond length is a little bit more than covalent bonds.
The range of the length of a hydrogen atom is $1.75\mathring{\text{A}}$ to $2.5\mathring{\text{A}}$
