Concept introduction:
Curved arrows are used to represent the movement of electrons in a reaction mechanism. The arrow starts on an electron-rich atom or an electron-rich region such as a pi bond. It ends on an electron poor atom when the movement results in the formation of a new sigma bond. If the result is the formation of a pi bond, the arrow ends in the region between the two atoms that form the bond.
A carbocation is a positively charged carbon atom that is electron-poor, two electrons short of an octet. A nearby bond or a lone pair on a nearby atom acts as an electron-rich region and can transfer the pair of electrons to the electron-poor atom. This can result in the formation of a more stable neutral species, accompanied by the loss of an electrophile. The electrophile may be a proton or another cationic species and is extracted by any base that may be present.
