Solution:

In (ethyl cation), the positively charged carbon atom has an empty -orbital. One of the bonds of the methyl group can align in the plane of this empty -orbital and the electrons constituting the bond in plane with this -orbital can then be delocalised into the empty -orbital as depicted below :
