Question

2. This question continues on the next two pages. The compounds that gave each ot the ollowing IR an alkene. Some of the compounds may contain more than one type of car (1 pt per spectrum 4 pts) spectra contain a carbonyl. Some of them also contain an aromatic ring and/or bonyl or CE low each spectrum indicate whether the compound contains an aldehyde, 1o amide, 20 amide, carboxylic acid, ester, ketone, or strained cyclic ketone. Below each spectrum indicate whether the compound contains an aromatic ring, an alkene, both or neither. b.

Answer 1

primary amine ,carbonyl saturated aldehyde,carboxylic acid

for saturated aldehyde peak should come at 1720-1740

for primary amine for two stretching vibration 3400-3500 peak will come

for carboxylic acid carbonyl peak will come around 2500-3300 and carbonyl of carboxylic acid will come around 1705-1720
