Carbocations

What is a carbocation?

A carbocation is a positively charged carbon atom with three bonds and no lone pairs, making it electron deficient.

What factors affect the stability of carbocations?

Factors like resonance stabilization, inductive effect, and hyperconjugation influence the stability of carbocations.

What is the stability order of carbocations?

The stability order of carbocations follows tertiary carbocation > secondary carbocation > primary carbocation due to increased electron-donating alkyl groups.

What is the molecular structure of a carbocation?

The molecular structure of a carbocation includes a carbon atom with a vacant p orbital, forming three bonds with neighboring atoms.

What are the differences between primary, secondary, and tertiary carbocations?

Primary carbocations have one alkyl group attached, secondary has two, and tertiary has three, affecting stability and reactivity.

Which carbocation is most stable?

The most stable carbocation is the tertiary carbocation because it has more alkyl groups attached, which provide greater electron donation, stabilizing the positive charge. Secondary carbocations come next, followed by primary and methyl carbocations in decreasing order of stability.



Carbocation: Definition, Structure, Properties and Formation

Carbocation is a molecule in which a carbon atom has a positive charge and three bonds. It is an electron-deficient species with an incomplete octet and is stabilized by adding a nucleophile, forming a new covalent bond. Carbocations are very reactive and unstable due to their incomplete octet.
