What will be the decreasing order of stability of following carbocations?
1 V $>$ IV $>$ III $>$ II $>$ I
2 I $>$ II $>$ III $>$ IV $>$ V
3 III $>$ V $>$ IV $>$ I $>$ II
4 I $>$ II $>$ III $>$ V $>$ IV
Explanation:
(B) : It is more stable due to presence of resonance in the compound. It is more stable than III due to presence of trialkyl amine, which activate the benzene ring. It is less stable than I \& II because it has deactivating group which destabilise the carbocation. It is least stable due to absence of conjugation at one side no extended conjugation present in molecule. It is least stable due to more electronegative of carbocation because it has sp hybridisation. Decreasing order of stability of carbocation \(\mathrm{I}>\mathrm{II}>\mathrm{III}>\mathrm{IV}>\mathrm{V}\)

Which of the following is the most stable compound?
The stability of carbocation is given by magnitude of charge as well as resonance effect. Resonance - when more than one structure is possible for a compound and explain all the properties of molecule. It also called canonical structure - It is more stable due to presence of more resonating structure and also it has $3^{\circ}$ carbocation. It also has 9 resonating structure hence it is more stable among all.

The following species generates a highly stable radical on exposure to $100 \mathrm{~W}$ bulb light. Which one of the following represents this stable radical?
Carbocation are those species which has positive charge on carbon atom. Stability of carbocation depends on resonance and magnitude of charge as the resonance increases and magnitude of charge so the stability of carbocation also increases. It shows equivalent resonating structure so it is more stable.
