CH3CH2CH2COHCH2CH3 +CH3CH2CH2CH2C=O H
the last reactant ends with a aldehyde, i was just not sure how to type it out. did my best.
i think the end product would be an hemiacetal because i'm adding an alchol to a aldehyde. it would be an acetal if i added an alchol to an acetal, right?

i meant to say it would be an acetal if i added an alcohol to a hemiacetal

Dr. David P. is indeed correct. If you just put the alcohol and aldehyde together, you would get a hemiacetal. That reaction is a simpkle addition and occurs spontaneously.You are also correct to say that reaction of a hemiacetal with alcohol would yield an acetal. However, that is a condensation, splitting out a molecule of water. You would have to add an acid such as H2SO4 or p-H3C-C6H4-SO3H and distil to drive out the water and shift the equilibrium. Sometimes people add a little benzene to distil out an azeotrope of benzene, alcohol, and water.

Hemiacetal.
PrCH(OH)-Et + Pr-CHO --> Pr-CH(OH)-O-CH(Pr)-Et
reaction with a ketone and an alcohol gives an acetal.
reaction of a aldehyde and an alcohol gives an hemiacetal
