what is a primary halogenoalkane?
is where the carbon to which the halogen is attached is, itself, attached to only one other carbon
1 of 10
what is a secondary halogenoalkane?
is where the carbon to which the halogen is attached is, itself attached to two other carbons
2 of 10
what is a tertiary halogenoalkane?
is where the carbon to which the halogen is, itself, attached to three other carbons

what will prevent further substitution (free rad)
Excess alkane
4 of 10

to show the movement of a pair of electrons
5 of 10
what mechanisms do halogenoalkanes undergo?
nucleophillic subsitution
6 of 10
what is a nucleophile?
A species that can donate a lone pair of electrons
