Butane vs 2-methylpropane

WebAnswer: 2-methylpropane can be seen as a central C atom with 3 methyl groups connected to it, and 1 H atom. So we have 9 completely equivalent H atoms and 1 “special” one. If all H’s were equally reactive, we would expect a reaction mix of 90% 1-chloro-2-methylpropane and 10% 2-chloro-2-methylpro... WebThe major difference is that 2-methylpropane is a “branched” chain and butane is a straight chain hydrocarbon. The branched chain molecule is “more spherical” in shape and thus …
