What is the hybridization state of carbon in carbocations?

A carbocation is molecule in which a carbon atom bears three bonds and a positive charge.Carbocations are generally unstable because they do not have eight electrons to satisfy the octet rule. read more

One could reasonably assume a carbocation to have $\mathrm{sp^{3}}$ hybridization with an empty $\mathrm{sp^{3}}$ orbital giving positive charge. However, the reactivity of a carbocation more closely resembles $\mathrm{sp^{2}}$ hybridization with a trigonal planar molecular geometry. read more

These carbocations where the C + is adjacent to another carbon atom that has a double or triple bond have extra stability because of the overlap of the empty p orbital of the carbocation with the p orbitals of the π bond. read more
