we ll the one u gave is actually not structural....structural formula shows the arrangement like specifically.....so u can't give the diagrammatic representation......and even if u write it like this with the bonds....u will have to show each bond separately like.....u can't put the last part as C2H5.....it has to be CH2CH3....very specific

kk...thanks nid....

Put the rest of the structure as it is.....acid followed by alcohol......but while naming remember u name the alkyl(formed from alcohol) first and then the acid+oate
I'm dead tired...so im bound to say crap in this state....if u spot summin wrong lemme know.....

OH from the acid (lactic) is used, not ehanol. (alchol)
nid404:
I think I'm write abt this......OH from ethanol used....and H from acid.....
hence the formula of ester still has a double oxygen with the acid......this can be further confirmed as the ester is alkyl( which confirms there is no OH) + acid...+ate
