Complete answer: Because it can’t overlap with the system’s π orbitals, it can’t be stabilized via … Nettet24. sep. 2024 · Carbocation Structure. Carbocations typically have three substituents which makes the carbon sp 2 hybridized and gives the overall molecule a trigonal planar geometry. The carbocation's substituents are all in the same plane and have a bond angle of 120 o between them. The carbon atom in the carbocation is electron deficient; it only … poofy little girls dresses
