Question

Which type of bond is not present in $HN{O}_2$ molecules?

• A. Covalent
• B. Co-ordinate
• C. Ionic
• D. Ionic as well as co-ordinate

Answer 1

The correct option is D Ionic as well as co-ordinate


In the above molecules , polar covalent bond is present between $O$ and $H$ and non polar covalent bond is present between $N$ and $O$. Hence it lacks ionic and coordinate covalent bond.
