What is the major difference between the twodimensional and three dimensional models of ethane and methane? When might you choose to use a twodimensional model rather than a threedimensional model when representing one of the molecules?

The major difference is that the twodimensional model doesn't show the CH angles. For example, threedimensional models are needed to show stereoisomerism

3D  more specific and harder to draw, 2D  much easier and provides more details.
I sort of dragged it out for you :)
