A stereocentre may be chiral or achiral (e.g., maleic acid has two stereocentres, none of them is chiral). However, all chiral centres are stereocentres - an atom having tetrahedrally bonded to four different atoms or groups is known as chiral centre. The C + of a carbocation uses s p2 hybrid orbitals, i.e., it has a flat geometry and hence it has a plane of symmetry. A chiral centre may be C , N , S , P , Si, etc.
