The SN₁ substitution reaction, in which the halogen is released from the haloalkane, and the nucleophile attacks the carbon's positive charge. SN₂ in which the nucleophile attacks the halogen's carbon, causing the halogen to be replaced in which nucleophile attack.
Substitution reactions are those reactions in which one functional group is replaced by another functional group.
Two types of substitution reactions can occur in haloalkanes: SN1 and SN2.
Thus, the SN₁ substitution reaction, in which the halogen is released from the haloalkane, and the nucleophile attacks the carbon's positive charge. SN₂ in which the nucleophile attacks the halogen's carbon, causing the halogen to be replaced in which nucleophile attack.
