By arthur winter you can locate carbonyl groups, alkenes, alkynes, and aromatics in the ir (infrared) spectrum, based on their shapes and relative locations. Adding h2o (water) to a pi bond is known as hydration • alkenes and alkynes are both nucleophilic due to the presence of pi bonds, meaning they react. Now the reason why alkynes are more acidic than alkenes, which are in turn more acidic than alkanes, is that sp carbon atoms are more electronegative than .
