MCQ
Compare $x$ and $y$  bond angles in the following molecule
  • ✓
    $x > y$
  • B
    $y > x$
  • C
    $x = y$
  • D
    None of these
✓

Answer

Correct option: A.
$x > y$
a
Chlorine is more electronegative than oxygen. Hence, the bond pair of electrons are more towards chlorine than towards oxygen. Hence, $S - Cl$ bond pair of electrons experience less repulsion than $S = O$ bond pair of electrons. Hence, the bond angle $x$ is greater than the bond angle $y$.
