Which fo the following carbocations is least stable ?A. `CH_(3)overset(+)CH_(2)`B. `CH_(2)=overset(+)CH`C. `CHequivC^(+)`D. `C_(6)H_(5)^(+).` |

Answer» Correct Answer - A `CH_(3)overset(+)CH_(2)` is the most stable carbocation. This can be explained as follows. The electronegativity of carbon increases as its hybridisation from `sp^(3)`. to `sp^(2)` to sp i.e., carbon which is `sp^(3)`-hybridised is least electronegative and `sp^(2)`-hybridised carbon is most electronegative. An element with least electronegativity can best accommodate + ve charge. In `CH_(3)overset(+)CH_(2)`, carbon is `sp^(3)` hybridised |
