Explanation / Answer

1)

N2 forms triple bond while others have single or double bond

So,Bond energy is maximum for N2

Answer: C

2)

O2 forms double bond while other forms single or triple bond

So, bond order of O2 is 2

Answer: B

3)

Cl2 will have longest bond length due to large size of atom Cl

Answer: E

4)

S forms 4 bond and has a lone pair

So, its shape is Square pyramidal

Answer: E
