Question

State True or False.

All molecules having polar bonds are polar.

• A. True
• B. False

Answer 1

The correct option is B False

The given statement is False.
Not all molecules having polar bonds are polar. An example is linear carbon dioxide molecule $\left(C{O}_2\right)$. The individual $C-O$ bonds are polar but the molecule on the whole is non polar as individual bond dipoles cancel each other. Another example is boron trifluoride $\left(B{F}_3\right)$ molecule with triangular planar geometry. Another example is carbon tetrachloride $\left(CC{l}_4\right)$ with tetrahedral geometry.
