(a) Excluding enantiomers, free-radical chlorination of bicyclo[2.2.1]heptane yields four monochloro derivatives but bicyclo[2.2.2]octane gives only two. Draw structural formulas for each.

(b) Which of the compounds in your answer to part (a) are chiral? Draw the structural formula of the enantiomer of each chiral monochloro derivative.
