For anything other than the most simple molecules, drawing a fully displayed formula is a bit of a bother - especially all the carbon-hydrogen bonds. You can simplify the formula by writing, for example, CH 3 or CH 2 instead of showing all these bonds. So for example, ethanoic acid would be shown ... WebTake, for example, ethane which contains the bond sequence H-C-C-H. The ethane is free to rotate about the C-C sigma bond, but in the eclipsed conformation, the C-H bonds on either end of the molecule are aligned with each other. Torsional strain arises from the electrons in one C-H repelling those in the C-H bond on the other end of the molecule. greer chiropractic
