What is the major product of the reaction between CH2=C=O and CH3CH2OH?

[Ahmed Abdullah]

The attempt at a solution
I tried and found two possible product CH2=C(OH)-O-CH2CH3 and CH3-COOCH3CH2 (ester).

But i am not sure which one, even whether any of them is.

Are you familiar with tautomerization?

Good hint, Bomba!

yep, keto-enol tautomerism...
so the major product should be CH3CO-O-CH2CH3...
