2
Statement 1: Oxygen does not possess 𝑑- orbitals in their valency shell
Statement 2: The covalency of oxygen is two
3
Statement 1: NaCl is more ionic than NaI.
Statement 2: Chlorine is more electronegative than iodine.
4
Statement 1: Bond energy has order like𝐶 − 𝐶 <= 𝐶 < 𝐶≡𝐶
Statement 2: Bond energy increases with increase in bond order
5
Statement 1: 𝑜 𝑜
All 𝐹 − 𝑆 − 𝐹 angle in 𝑆𝐹4 is greater than 90 but less than bond 180 .
