In the carbon family , the elements other than carbon do not form pn-p pi nonds because the atomic orbitals are :

Assertion : Carbon has unique ability to form p pi-p pi multiple bonds with itself and with other atomic of small size and high electronegativety. Reason : Heaviur elements of group 14th do not form p pi -p pi bonds because their atomic orbital are too large and diffuse to have effective sideways overapping.

A : Heavier elements of 14th group do not form p pi - p pi bonds . R : Atomic orbital of heavier elements are too large and do not have effective overlapping .
