You'll get a detailed solution from a subject matter expert that helps you learn core concepts. In contrast, the condensed structural formula for the isomer 2-methylpropane (sometimes called isobutane) is (CH 3) 2 CHCH 3, in which the primary chain of three carbon atoms has a one-carbon chain branching at the central carbon. But structure V is less stable due to presence of positive charge on electronegative oxygen (O) atom. ; McGorrin, R.J., Gas chromatography-mass spectroscopy investigations on the flavor chemistry of oat groats, J.
