It is a forum rule (see red link above) that you must show your attempt before we can help you. What factors stabilize carbocations?
Sorry sir, I am new on this forum so I don't know the rule.Ok, I am telling you How I approach this Problem. Here in this question ask to find stable carbocation.And as per my knowledge, I know that Carbocation can be stabled by +I effect and Resonance.In the number 1 option, There is a possibility of resonance, so I think that this resonance can stabilize the carbonation.But the answer is wrong.The correct option is 2.Now please explain sir. @Babcock_Hall
