1.	20. Which of the following is most stable carbocation?CH2(d) CH2 CH-CH2
Answer» Carbocations are always hungry forelectrons. The stability of carbocations increases from primary to secondary to tertiary. Here, option (c) shows the most stable carbocation because, it can easily withdraw electrons from two other carbon atoms and the more electronegative oxygen atom. Carbocation stability depends on hyperconjugation. Hyperconjugation is the interaction of electrons present in sigma bonds of C-C or C-H atoms with the electrons present in an adjacent empty non-bonding p orbital, which gives extended molecular orbital, is the cause of stability of carbocations.
