2,2,4-Trimethylpentane (isooctane), $(CH X_{3}) X_{3} C - CH X_{2} - CH (CH X_{3}) X_{2}$ , is monochlorinated. The number of structural isomers of the product $C X_{8} H X_{17} Cl$ is

Distinct H types: the three methyls of the tert-butyl group (1), the

CH X_{2}

(2), the

CH

(3), and the two equivalent methyls on that CH (4). So 4.
