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

1. The major difference is that the two-dimensional model doesn't show the C-H angles. For example, three-dimensional models are needed to show stereo-isomerism

2. 3D - more specific and harder to draw, 2D - much easier and provides more details.

I sort of dragged it out for you :)

5. FIRST: well uh...the two dimensional model of the methane shows the carbon atom bonded to 4 hydro. atoms and i think the ethane one shows its bound by only 2

SECOND: and i believe they differ because methane is tetrahedal and ethane is trigonal pyramidal

your welcome because everyone else is an 🥺❤
