Vedclass · Answer

(D) The order in '$A$' is correct because the bond angle decreases as the electronegativity of the central atom decreases down the group,leading to less repulsion between bond pairs.The order in '$B$' is correct because the electron density on the central atom decreases as the size of the atom increases,making the lone pair less available for donation.The order in '$C$' is incorrect because thermal stability decreases down the group due to the increase in bond length and decrease in bond dissociation energy. The correct order is $NH_3 > PH_3 > AsH_3 > SbH_3$.The order in '$D$' is correct. $NH_3$ has a high boiling point due to intermolecular $H$-bonding,while for the others $(PH_3, AsH_3, SbH_3)$,the boiling point increases down the group due to increasing van der Waals forces (molecular weight).Thus,the correct orders are $A, B$ and $D$.

Identify the correct orders from the following with respect to the property associated with:
$A$. $NH_3 > PH_3 > AsH_3 > SbH_3$ - Bond Angle
$B$. $NH_3 > PH_3 > AsH_3 > SbH_3$ - Basic Character
$C$. $PH_3 > AsH_3 > SbH_3 > NH_3$ - Thermal stability
$D$. $SbH_3 > NH_3 > AsH_3 > PH_3$ - Boiling point
