$90$

Vedclass · Answer

(A) In the corresponding compound $NH_3$,the bond angle is $107^o$.However,in $PH_3$,the bond angle is approximately $90^o$.This is because,despite having a similar electronic structure,the electronegativity of the central atom $(P)$ is lower than that of $N$. As a result,the bonding electrons are further from the central atom,reducing the $bp-bp$ repulsion and causing the bond angle to decrease towards $90^o$.

$I. SnCl_2$	$II. BeF_2$
$III. SO_2$	$IV. NO_2^+$
$V. C_2H_2$

The bond angle in $PH_3$ is closest to which of the following $^o$?
