Hi i have a quick question i'm supposed to show how isoamyl propanoate is fromed. I know that this is esterification and that one of the reactants is propanoic acid but i don't know what the alcohol isoamyl is? I tried searching on google and all i get is test questions:mad: Plz help

n-amyl alcohol = pentan-1-ol

iso-amyl alcohol = isopentyl alcohol, 3-methyl-1-butanol
(CH3)2CHCH2CH2OH

both are C5H12O

Are you sure it isn't 1-methyl-1-butanol, i checked the link but it doesn't seem right

doesn't isopentyl mean that the OH group is attached to the second Carbon, so how would you get 3-methyl-1-butanol. If that is right (3-methyl-1-butanol) then would isoamyl propanoate be the same as 3-methylbutyl propanoate?
