Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(Q) = CO₂

The central carbon atom forms two $\sigma$ bonds, leading to sp hybridization.

The structure is linear (O=C=O), hence planar.

(R) = [P₄O₁₂]⁴⁻

It is a cyclic metaphosphate ion.

Each phosphorus atom is sp³ hybridized and exhibits P–O–P (X–O–X) linkage.

Therefore, the correct matching is:

Q → sp (IV), planar (iii)

R → sp³ (II), X–O–X linkage (ii)

Correct option: (B)
