The alkane called Butane has C-C bonds. It is a little different than that of ethane. ... In organic chemistry, we have functional groups that are responsible for the reactivity of a … WebNote that (2) can be obtained from (1) by rotating the C-C bond by 60 degrees. Unlike in the case of alkanes, the eclipsed form is more stable, not the bisected form. This can be easily accounted for: In the eclipsed … Web4.1.1 Conformation. At a molecular level, a property of σ (sigma) bonds in alkane is that the bonds keep on rotating. For the example of ethane (CH 3 CH 3 ), one methyl (CH 3) group is able to rotate around the C-C bond freely without any obstacles. It is highly recommended that the molecular model is used here to “see” the bond rotation. jf rカード解約
