प्रश्न
Find out the most stable species from the following. Justify.
\[\ce{\overset{+}{C}H3, \overset{+}{C}H2Cl, \overset{+}{C}Cl3}\]
उत्तर
The most stable species from the given species is `overset(+)("CH"_3)`
This because it does not contain Cl atom, which exhibits an electron-withdrawing inductive effect. Carbocations are destabilized by -I inductive (electron-withdrawing) effect. When more number of –I groups are attached to the positively charged carbon atom, the positive charge on the carbon atom increases further, thus destabilizing the species. Hence, the species with no –I groups will be most stable.
