    				| 1. | 4)In a carbocation, the central carbon atom involved | 
| Answer» Acarbocationforms bonds with three other groups and is positively charged. With three bond pairs and zero lone pairs it has trigonal planar geometry by VSEPR theory, and trigonal planar is characteristic ofsp2 hybridisation. ... Therefore, it needs 3hybridisedorbitals, so it issp2 hybridised. | |
