What is meant by hybridisation ? Compound CH_(2)= C= CH_(2) contains sp or sp^(2)-hybridised carbon atoms. Will it be a planar molecule ? |
Answer» Solution :Defination: The phenomenon of mixing of atomic ORBITALS of same ATOM having MUCH less diffrence in their energy to form equal no of orbitals having similar. These compound contains sp and `sp^(2)` hybridised CARBON atom STRUCTURE of allene `(C_(3)H_(4))` is,  Allene molecule `CH_(2)= CH_(2)` is not planar  According to figure: `pi (2p_(y) -2p_(y)) bot pi (2p_(z)-2p_(z))` `C_(1)` carbon is `sp^(2)` and (H)a and (H)b lie in a plane perpendicular to the plane of the paper so (H)a is up and (H)b is bottom. `C_(1), C_(2) and C_(3)` are linear. `C_(3)` carbon is `sp^(2)` and (H)c and (H)d lie in the plane of paper `[("The plane of"),("(H)c adn (H)d")] bot [("The plane of"),("(H)a and (H)b")]` Thus, the all molecule of allene is non-planar |
