Question

Assuming Covalent bonding between $Na$ and $Cl$, What is the expected bond order ?

• A. $1.5$
• B. $1$
• C. $2$
• D. $0$

Answer 1

Answer: (B)

$1$

Bond order is the number of chemical bonds between a pair of atoms.For example, in diatomic nitrogen $N\equiv N$ the bond order is $3$. Bond order gives an indication of the stability of a bond. In the similar fashion assuming covalent bonding between Na and Cl, expected bond order is $1.$
