Answer #1

It is very difficult to predict the exact molecule because with IR we can only say about the functionality. The main concern of not giving the exact formula because both pentenoic acid as well as butenoic acis will show the same IR feature. Therefore, without knowing the empirical formula I cant provide the exact molecule.

Hope you will understand my situation. Thanks.The broad band around w3200 cmt signify the presence of - on functional The shaup stretching frequency at 1688 cmt is of carb
