Covalent Bond Chemistry Example 2

Solution

1. 1
   Single bond: 1 shared pair (2 electrons). Example: $\text{H–H}$ in $\text{H}_2$.
2. 2
   Double bond: 2 shared pairs (4 electrons). Example: $\text{O=O}$ in $\text{O}_2$.
3. 3
   Triple bond: 3 shared pairs (6 electrons). Example: $\text{N≡N}$ in $\text{N}_2$.
4. 4
   Bond strength increases and bond length decreases as the number of shared pairs increases.
