The shape of methyl carbocation is likely to be

Answer»

tetrahedral
pyramidal
planar
linear

Solution :Carbocations are formed by heterolytic bond fission.
`-overset(|) underset(|)C-Z to -overset(|) underset(|)C+Z^(-)`
In `CH_(3)^(+)`, the carbon ATOM is `SP^(2)`- hybridised , so the carbon atom used `sp^(2)` hybrid orbitals to formthree `SIGMA` bonds. A empty p-orbitalis symmetrically above and below the plane of three sigma bonds. This empty p-orbital makes the carbon atom electron-defincient (eelectrophile). The three `sp^(2)` hybrid orbitalsare directed towards the CORNERS of a equilateral triangle. Hence, the shape of `CH_(3)^(+)` is likely to be planar.
