Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques
The correct stability order of the following carbocations is : (I)H2C⨁-CH=CH-CH3, (II)⨁CH2-CH=CH-BMe2, (III)H2C⨁-CH=CH-NMe2, (IV)H2C⨁-CH=CH-OMe
A
II>I>III>IV
B
III>I>II>IV
C
III>IV>I>II
D
IV>III>II>I
Answer
III>IV>I>II
Explanation
Solution
The correct stability order of the given carbocations is:
(I) H2C⁺-CH=CH-CH3 (III) H2C⁺-CH=CH-NMe2 (IV) H2C⁺-CH=CH-OMe (II) ⁺CH2-CH=CH-BMe2
The order is based on the stability of carbocations, which is influenced by factors such as the nature of the substituents and resonance effects. The stability generally increases with the presence of electron-donating groups or resonance stabilization.
The correct option is(C): III>IV>I>II
