I was given an introductory question into Carbonyl chemistry today and I wanted to ask a question about Methanal.
The following picture was shown below of Methanal:
and I noted that the orbital sizes differed for both Carbon and Oxygen in the top and bottom diagrams. I thought one of these diagrams must be wrong.
I then knew that as Oxygen has more protons than Carbon, then its atomic radius is smaller, meaning the orbital size must be smaller too, so I thought that the bottom diagram represented the size of the p orbitals better both for anti bonding and bonding.
Is the diagram for $\pi$ bonding drawn correctly in terms of orbital size?
