The shape of carbocation is :

The shape of a carbocation is planar and it is sp2 hybridized.

Here are the steps to understand why:

1. A carbocation is a molecule in which a carbon atom bears three bonds and a positive charge.

2. The three bonds formed by the carbon atom are arranged in a plane.

3. The carbon atom in a carbocation is sp2 hybridized. In sp2 hybridization, one s orbital and two p orbitals in the carbon atom hybridize to form three new sp2 hybrid orbitals.

4. These sp2 hybrid orbitals are arranged in a trigonal planar geometry around the carbon atom.

5. The remaining unhybridized p orbital lies perpendicular to the plane of the three sp2 hybrid orbitals.

6. Therefore, the shape of a carbocation is planar.
