Thank you for your question.

Answer 2

Answer:

The pair with sp2 hybridization of central molecules is BF3 and NO2- option(c).

Explanation:

The hybridization of central atoms for molecules is calculated as $\frac{Total number of valence electrons of all atomes}{8}$

and the obtained value is known as coordination number.

    for BF3, coordination number = $\frac{24}{8}$ = 3

as when coordination number is 3 then hybridization will be sp2

so, the hybridization of BF3 will be sp2.

for ions, coordination number = $\frac{1}{2} ( 5+0-0+1) = 3$

so the hybridization of NO2- will be sp2.

The pair with sp2 hybridization of central molecules will be BF3 and NO2-.
