Class of carbocation
WebMar 13, 2024 · A carbocation is stabilized by adjacent lone pairs of the electron due to resonance. Now, coming to the question all the four molecules given in option get stabilized by hyperconjugation. Alpha hydrogen is that hydrogen that is attached to alpha carbon (first carbon atom that attaches to a functional group). WebPage 6 : , , A carbocation is an organic species, an intermediate, that, forms as a result of the loss of two valence electrons,, normally shared electrons, from a carbon atom that already, , has four bonds., , , This leads to the formation of a carbon atom bearing a, , positive charge and three bonds instead of four.

The different carbocations are named on the basis of the number of carbon groups bonded to the carbon. The carbocation can be termed as methyl, primary, secondary or tertiary on the basis of how many carbon atoms are attached to it: 1. Methyl carbocation: If no carbon is attached to the carbon with the … See more The carbocations can be formed by either of the following two fundamental steps: 1. Cleavage of a bond of carbon. 2. Electrophilic addition. See more The stability order of carbocation is as follows: The stability of carbocations depends on the following factors: 1.
