WebAlways draw alkenes with the correct 120° bond angles around the C=C bond as shown in the diagrams for the cis and trans isomers above. If you take a short cut and write but-2-ene as CH 3 CH=CHCH 3, you will almost certainly miss the fact that cis and trans forms are possible. This is a rich source of questions in an exam. WebThe commonest way to draw structural formulae. 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 ...
