Calculate 2 ( x + y ) ​ for given species BF 3 ​ , BeF 2 ​ , AlCl 3 ​ , NH 3 ​ , PCl 5 ​ , SF 6 ​ , CCl 4 ​ , IF 7 ​ , CO 2 ​ and XeF 4 ​ Where, x = Number of hypovalent species y = Number of hypervalent species

To find x (hypovalent) and y (hypervalent) species, we examine the central atom's octet.

Hypovalent (x): BF₃ (6e⁻), BeF₂ (4e⁻), AlCl₃ (6e⁻). So, x = 3.

Hypervalent (y): PCl₅ (10e⁻), SF₆ (12e⁻), IF₇ (14e⁻), XeF₄ (12e⁻). So, y = 4.

Normal octet: NH₃ (8e⁻), CCl₄ (8e⁻), CO₂ (8e⁻).

Calculate: $(x + y) /2 = (3 + 4) /2 = 7/2 = 3.5$ .
