Vedclass · Answer

(A) According to the $VSEPR$ theory,lone pairs are localized on the central atom,whereas bond pairs are shared between two atoms. Because lone pairs are attracted by only one nucleus,they occupy more space around the central atom compared to bond pairs,which are attracted by two nuclei. This increased spatial requirement leads to greater repulsive interactions between lone pairs than between lone pair-bond pair or bond pair-bond pair interactions. Thus,the Reason correctly explains the Assertion. Therefore,the correct option is $A$.

List-$I$ (Shape)	List-$II$ (Example)
$(1)$ Linear $(B-A-B)$	$(A)$ $PCl_5$
$(2)$ Trigonal planar	$(B)$ $CH_4$
$(3)$ Tetrahedral	$(C)$ $HgCl_2$
$(4)$ Trigonal bipyramidal	$(D)$ $BF_3$

Assertion : Lone pair-lone pair repulsive interactions are greater than lone pair-bond pair and bond pair-bond pair interactions.
Reason : The space occupied by lone pair electrons is more as compared to bond pair electrons.
