Are these molecules conjugated?

If Org 2 has an overall theme, it’s “resonance”. Today’s post has a very simple message. Atoms with lone pairs, π bonds, radicals, and carbocations can

The Single Swap Rule

I don’t think there are that many “tricks” to doing well in organic chemistry, but there are a few. I was kind of surprised last

The Meso Trap

Question: Are these molecules enantiomers, diastereomers, or the same? If you immediately recognized this as a molecule with an internal plane of symmetry (and thus

Calculating the oxidation state of a carbon

Try applying the rules for calculating oxidation states to carbon.

It’s going to feel a little bit weird. Why? Because there are two key differences.

First, carbon is often more electronegative (2.5) than some of the atoms it’s bound to (such as H, 2.2). So what do you do in this case?
Secondly, unlike metal-metal bonds, carbon-carbon bonds are ubiquitous. So how do you deal with them?
