The molecular plane

A plane parallel to the molecular plane

A plane perpendicular to the molecular plane which bisects the carbon-carbon σ-bond at right angle

A plane perpendicular to the molecular plane which contains the carbon-carbon σ-bond

Maximum polarization is brought about by a cation of high charge.

Minimum polarization is brought about by a cation of small radius

A large cation is likely to bring about a large degree of polarization.

A small anion is likely to undergo a large degree of polarization.

A covalent bond is formed by the overlapping of orbitals with unpaired electrons of opposite spins.

A covalent bond is formed by the overlapping of orbitals with unpaired electrons of same spins.

The greater the extent of overlapping the stronger is the bond.

Overlapping takes place only in the direction of maximum electron density of the orbital.
