Question

What is carbocation and carboanion? Please explain.​

Answer 1

Answer:

A carbocation (/ˌkɑːrboʊˈkætaɪən/[1]) is an ion with a positively charged carbon atom. Among the simplest examples are the methenium CH+

3, methanium CH+

5 and vinyl C

2H+

3 cations. Occasionally, carbocations that bear more than one positively charged carbon atom are also encountered (e.g., ethylene dication C

2H2+

4).[2]

carbanion is an anion in which carbon is trivalent (forms three bonds) and bears a formal negative charge (in at least one significant resonance form).[1] Absent π delocalization, carbanions assume a trigonal pyramidal, bent, or linear geometry when the carbanionic carbon is bound to three (e.g., methyl anion), two (e.g., phenyl anion), or one (e.g., acetylide anion) substituents, respectively. Formally, a carbanion is the conjugate base of a carbon acid:

Answer 2

$\Large\underline{\underline{\sf \red{Carbocation}:}}$

Carbon in which positive charge is present in carbon atom is called Carbocation.

• Due to electron deficiency it acts as an electrophile and always attack on electron richer site.

• It is incomplete octet species because it has six electron in outer most shell.

$\Large\underline{\underline{\sf \red{Carboanion}:}}$

Anion in which negative charge is present on carbon atom is called Carboanion.

• It has 8 electron in Outermost shell so it is Complete octet species

• It is an electron richer species because it has extra electron

• Due to presence of non bonding electron it act as a nucleophile.
