MCQ
Which has maximum bond angle
  • ✓
    $CH{F_3}$
  • B
    $CHC{l_3}$
  • C
    $CHB{r_3}$
  • D
    All have maximum bond angle
✓

Answer

Correct option: A.
$CH{F_3}$
a
Bond angle depends on repulsion among the Bond pair electrons. In these cases we have to see the electronegativity of halogen atoms. the more is electronegativity of halogen atom the more they bond pair electron remain away from carbon nucleus and lesser is the repulsion. So lesser is the Bond angle.So, have bond angle order is

$CHF _3\,<\, CHCl _3\,<\, CHBr _3$
