    For example, (CH 3) 2 CHCH 2 CH 3 (isopentane) is named 2-methylbutane, not 3-methylbutane. If there are multiple side-branches of the same size alkyl group, their positions are separated by commas and the group prefixed with multiplier prefixes depending on the number of branches. For example, C(CH 3) 4 (neopentane) is named 2,2 ...
