Answer the question number 3
Dear Student,
When halide ion of alkali metal halides are missing from lattice causes a hole leads to F-centres which absorbs white light from the surroundings and forms colour in emission process. Hence alkyl halides forms colour during excitation and no colour in ground state.
Regards.
