The linear triatomic molecules of the type

B - A - B

e.g.

C O_{2}

have no dipole moment, not because the individual

C = O

bonds are non-polar but because the two bond moments (polarity) cancel each other.

Therefore, geometry of molecules can be predicted by the value of dipole moment.

If both Assertion and Reason are false

The linear triatomic molecules of the type B−A−B e.g. CO2​ have no dipole moment, not because the individual C=O bonds are non-polar but because the two bond moments (polarity) cancel each other. Therefore, geometry of molecules can be predicted by the value of dipole moment.

Q. Assertion: The dipole moment helps to predict whether a molecule is polar or non-polar.
Reason: The dipole moment helps to predict geometry of molecules.

The linear triatomic molecules of the type $B - A - B$ e.g.

$C O_{2}$ have no dipole moment, not because the individual $C = O$ bonds are non-polar but because the two bond moments (polarity) cancel each other.

Therefore, geometry of molecules can be predicted by the value of dipole moment.
