Which statement explains why halogenoalkanes react with nucleophiles?
The bond between carbon and the halogen in all halogenoalkanes is ionic so nucleophiles are attracted to the positive carbon ion.
The small atomic radius of a carbon atom enables the six protons in its nucleus to attract nucleophiles.
The carbon atom bonded to the halogen atom has a vacant orbital which can accept a pair of electrons.
Because halogens are more electronegative than carbon they attract the bonding pair of electrons more strongly making the carbon atom electron deficient with a small positive charge, δ+.
