Explain why rotation about carbon-carbon double bond is hindered ?

Explain the formation of carbon-carbon double bond in ethene.

Ordinarily the barrier to rotation about a carbon - carbon double bond is quite high but in compound P double bond between two rings was observed by NMR to have a rotational energy barrier of only about 20 cal/mol., showing that it has lot of single bond character. The reason for this is

Geometrical isomerism arises due to restricted rotation about carbon-carbon or carbon-nitrogen double bond

Carbon-oxygen double bond is called

The organic compound having a double carbon-carbon covalent bond is :
