There's a question about inhibition of resonance:

Is steric inhibition of resonance or steric inhibition of protonation dominant in o-toluidine?

If you look at Martin's answer he says that CH3 is not bulky enough to cause steric inhibition of resonance. What if I considered a group such as ethyl or propyl or even bulkier, then would we observe SIP (steric inhibition of protonation) as well as steric inhibition of resonance?

What would dominate?
