Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Read the two carbons along the line of sight : the front carbon carries CH₃, CH₃, H and the back carbon carries CH₃, H, H, so the skeleton is (CH₃)₂CH-CH₂CH₃ = 2-methylbutane. (A) propane has too few carbons; (C) is 2-methylpropane, which would show CH₃, CH₃, H on one carbon and H, H, H on the other; (D) would require an ethyl group on the back carbon.
