Primary is more reactive than secondary and tertiary alkyl halides.

WebIn a substitution reaction, one atom (or a functional group) replaces another one. The replacing group is called a “ nucleophile ” and the group being kicked out is called a “ leaving group ”: These reactions occur because of the imbalance of the electron density between the carbon and halogen (leaving group) since it is a polar covalent bond.

"WebNov 21, 2014 · Explanation: Consider a general nucleophilic substitution reaction. The second arrow always shows a pair of electrons going toward the leaving group. The best leaving groups "want" those electrons. They don't want to share them with other atoms. Good leaving groups are weak bases. Weak bases have strong conjugate acids.
