The most stable carbocation for the following is:
The Correct Option is C
Solution and Explanation
The most stable carbocation is (c). The stability of the carbocation is enhanced by the +M (mesomeric) effect of the \( \text{NH}_2 \) group, which donates electron density into the ring, stabilizing the positive charge on the carbocation. In this case, the resonance structures show that the positive charge is delocalized, making this carbocation the most stable.
Thus, the correct answer is:C

Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
