So starting with a, we're looking for six atoms that bond to carbon commonly in organic compounds.
00:07
So the first two should be hydrogen and carbon, considering those form the basis of a lot of organic compounds, especially when a carbon binds to itself.
00:20
Next, we can do oxygen and nitrogen, both of which show up a lot in organic compounds.
00:26
And the last two are going to be sulfur and phosphorus.
00:29
All right, so b is asking which ones are heteroatoms.
00:35
And that's a term that basically means everything except for carbon and hydrogen.
00:39
So in this case, it's going to be oxygen, nitrogen, sulfur, and phosphorus...
