Multiple Line Structures

Postby Kevin_Li_2F » Tue Feb 28, 2017 8:12 pm

When drawing line structures, what makes one line structure more valid/correct than another? For example...

All represent 3,3-dimethylpentane, yet each differ slightly by bond angle or whether a line turns up or down.

Is there a standardized correct method for these line structures? For example I've noticed that when 3 lines come together, they tend to do so at congruent 120 degree angles, and 90 degrees for four lines.

You want to make your line structures still indicative of the bond angles. So this goes back to chem 14a so for example when you have a trigonal planar shape your angles will be close to 120 degrees.
