Question

Match List-1 with List-2.

Column 1	Column 2
${\mathrm{Ne}}_2$	1
${\mathrm{N}}_2$	2
${\mathrm{F}}_2$	0
${\mathrm{O}}_2$	3

Answer 1

Bond Order: The number of chemical bonds between a pair of atoms, or bond order, determines how stable a bond is. Bond order is inversely proportional to bond strength. The following formula is used to find the bond order-

Bond order = $\frac{\mathrm{number}\mathrm{of}\mathrm{electron}\mathrm{in}\mathrm{bonding}-\mathrm{number}\mathrm{of}\mathrm{electron}\mathrm{in}\mathrm{antibonding}}{2}$

1. ${\mathrm{Ne}}_2$ has a bond order is zero.
2. ${\mathrm{N}}_2$ has bond order 3.
3. ${\mathrm{F}}_2$ has bond order 1.
4. ${\mathrm{O}}_2$ has bond order 2.

Final Answer: The correct match is-

List-1	List-2
${\mathrm{Ne}}_2$	0
${\mathrm{N}}_2$	3
${\mathrm{F}}_2$	1
${\mathrm{O}}_2$	2
