Question

Consider two covalent compounds $AL_{n_1}$ and $BL_{n_2}$, if central atom (A) of first compounds has total six electron pairs and central atom (B) of second compound contains total five electron pairs in its valence shell and both compounds are planar and non-polar then calculate value of expression $(n_1 - n_2)^2$.

Correct answer: 4

**SOLUTION:** $\RIGHTARROW$ NUMBER OF ELECTRON PAIR ON A = 6 $\RIGHTARROW$ NON-POLAR, PLANAR. HENCE $N_1 = 4$
$\RIGHTARROW$ NUMBER OF ELECTRON PAIR ON B = 5 $\RIGHTARROW$ NON-POLAR, PLANAR. HENCE $N_2 = 2$
$(N_1 - N_2)^2 = (4 - 2)^2 = 4$
