Oxidation without cleavage of sigma bond takes place in alkenes.
Presence of unsaturation· -in alkenes is detected by using Baeyer's reagent. Alkenes decolourise pink colour of Baeyer’s. reagent. In presence of Baeyer's reagent, 'syn' addition of-OH groups takes place on both carbons· of double· bond. The net reaction can be given as,
Ozonolysis of· alkenes give ozonide, which on further hydrolysis gives aldehyde and/or ketone.
Linear polyenes on. ozonolysis gives two moles of acetaldehyde and one mole of propanedial. Linear polyene will be:

Hydrogenation of alkenes and alkynes takes place in presence of certain catalysts. In Sabatier Senderen's reaction, the. addition ·of hydrogen takes·· place in presence of Raney nickel· catalyst. Platinum and palladium can also be used as catalyst in these reactions. These are heterogeneous catalyst and used in. finely. divided state. Experimentally, it is observed that less. crowded alkenes adsorb H2 with faster rate. Controlled hydrogeneration of alkyne in presence of Lindlar's catalyst yields cis product i.e., 'cis' alkene. Thus, in presence of Lindlar's catalyst 'syn' addition takes place. The relative rate of hydrogenation follows the order:
Non-terminal alkynes an reduce4 in presence of Na or Li metal dissolved in liquid ammonia. In this reaction, anti-addition of hydrogen results into the trans-product. .
The product of the following reaction is:
