Writing formula from diagram

Postby akroberts » Wed Oct 03, 2018 1:26 pm

What's the best technique for writing a molecular formula when given a diagram of its structure (exercises F1/2)?

For exercises F1 I just counted the number of carbons, hydrogens, and oxygens that I saw on the diagram, using the given code. For F1 I got C10H16O.

Look at how many atoms of each color there are and write the formula based off of the key it gives you.
Eg. F1 (7th edition). Dark grey = C, White = H, Red = O
10 Dark grey atoms
16 white atoms
1 red atom
Molecular formula - C10H16O
The order in which you put the atoms doesn't really matter.
