Sapling #20

Postby Rose_Malki_3G » Sun Nov 15, 2020 11:01 pm

In #20 of the sapling assignment it asks you to choose which intermolecular forces of attraction are present between CH3CHO molecule. I was wondering why hydrogen bonding cannot be present here by connecting the oxygen atom to one of the hydrogen atoms?

Hi! So when you draw out the CH3CHO molecule you see that the hydrogen doesn't actually bond to the oxygen, only carbon. The oxygen bonds to a carbon. Therefore, there isn't a O-H bond present, so hydrogen bonding is not a factor.

Hello Rose, I agree with Sophia, to my understanding it was because the Aldehydes have a "polar carbonyl group" and no O-H bond.
