Acyl transfer (nucleophilic substitution at carbonyl) reactions proceed in two stages via a "tetrahedral intermediate." Draw the tetrahedral intermediate as it is first formed in the following reaction. H3C. ... NH2 HCI/H₂O reflux • You do not have to consider stereochemistry. • Include all valence lone pairs in your answer. • Do not include counter-ions, e.g., Na+, I, in your answer. • In cases where there is more than one answer, just draw one. + 4 n [ ?

Do hydration reactions like this one have Markovnikov and anti-Markovnikov products? I know that for addition of halides on alkene double bonds, there are Markovnikov products becasue of 1,2-halide/methyl shifts, but there usually aren't shifts in hydration reactions.  Essentially, would the Markovnikov/major product for this reaction have a hydroxy group attached to the tertiary carbocation and the anti-Markovnikov/minor product for this reaction have a hydroxy group attached to the adjacent secondary carbocation?
