What is the hybridization of oxygen or nitrogen in each of the following?

 

Video Transcript

Alright everyone, so it's our job to calculate the hybridization of our oxygen group. Now, notice that if we were to draw this out in bond line what we would get is we would get this ether group, right? A symmetrical ether. Remember, that this oxygen is going to have two sets of lone pairs, okay? So let's show that, we have a lone pair here and a lone pair here, so when we do hybridization is we ask ourselves how many things is attached to, we're going to do is attach to two carbons and it has two lone pairs, two sets of them. So, in total is going to be attached to four different things, okay? Don't forget to count those lone pairs. So, four things being attached to means the hybridization is sp3, okay? So, we're going to say that this oxygen right here as a part of this ether is actually sp3 hybridized. Alright so, let me know if you have any questions.

The number of chemical bonds between two atoms is described by the  bond order. For example, a single bond has a bond order of 1, and a triple bond has a bond order of 3. In a resonance hybrid, the bond order need not be an integer quantity! Look at the carbon-carbon bond labeled  38 in the structure of atenolol above.
