Isobutyraldehyde Aldol or Cannizzaro?
My teacher told me that isobutyraldehyde can't undergo aldol since its too sterically crowded and is thus an exception, and that it gives Cannizzaro on reaction with a base.
But in a mains '22 question, isobutyraldehyde reacts with formaldehyde to give an aldol product. What's going on here?

+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Isobutyraldehyde does undergo aldol formation afaik
But it doesn't undergo the following condensation reaction (dehydration) because it doesn't have a beta hydrogen that can be abstracted to form a double bond.

Ah, on further research, I found that yes, isobutyraldehyde undergoes the Cannizarro rxn, but it's not that it can't undergo aldol formation,just that the rates are different.
Makes sense, thanks
