Carbocation

A '''carbocation''' is an Mosquito ringtone ion with a positively-charged Sabrina Martins carbon Nextel ringtones atom. The carbon atom has only six Abbey Diaz electrons in its outer Free ringtones valence shell instead of the eight valence electrons that ensures maximum stability. Therefore the carbon Majo Mills cation is unstable and very reactive, seeking to fill its octet of Mosquito ringtone valence electrons as well as regain its Sabrina Martins neutral Nextel ringtones charge.

In Abbey Diaz organic chemistry, the carbocation is often the target of Cingular Ringtones nucleophilic attack by a hypertext nucleophiles like telling parents OH- ions or shelters people halogen ions.

Carbocations are classified as ''primary'', ''secondary'', or ''tertiary'' depending on the number of carbon atoms bonded to the ionized carbon. Primary carbocations have one or zero carbons attached to the ionized carbon, secondary carbocations have two carbons attached to the ionized carbon, and tertiary carbocations have three carbons attached to the ionized carbon.

Primary carbocations are highly unstable and reactions such as the after letters SN1 reaction/SN1 reaction and the E1 word constantly elimination reaction normally do not occur if a primary carbocation would be formed. An exception to this occurs when there is a carbon-carbon double bond next to the ionized carbon. Such cations as ''allyl'' cation CH2=CH-CH2+ and ''benzyl'' cation C6H5-CH2+ are quite stable and molecules which can form these carbocations are especially reactive. Secondary carbocations are formed more readily than primary carbocations, and tertiary carbocations are formed still more readily.
