,FAsF bond angle in AsF_3Cl_2 molecule is - Vidyadip

MCQ

$\angle \,FAsF$ bond angle in $AsF_3Cl_2$ molecule is

✓
$90^o$ and $180^o$
B
$120^o$
C
$90^o$
D
$180^o$

✓

Answer

Correct option: A.

$90^o$ and $180^o$

a
The answer is $90$ and $180$ because axial positions prefer high electronegative atoms so $2$ fluorines on axial and one on eguitorial axial positions prefer high electronegative atoms due to bents rule as they repulsion is more for electronegative aoms
