Obtaining Aldehydes from Alkenes

To obtain aldehydes from alkenes, one common method is through the process of ozonolysis. Ozonolysis is a chemical reaction that involves the cleavage of carbon-carbon double bonds by ozone (O3). This reaction can be used to convert alkenes into aldehydes among other products.

Ozonolysis Reaction: The general ozonolysis reaction of alkenes to aldehydes can be represented as follows: ``` RCH=CHR' + O3 → RCHO + R'CHO ``` Where R and R' represent the alkyl or aryl groups.

Ozonolysis of alkenes results in the formation of aldehydes as one of the products. This process involves the cleavage of the carbon-carbon double bond and the addition of oxygen to form aldehyde functional groups.

Example: An example of obtaining an aldehyde from an alkene through ozonolysis is the conversion of ethene (ethylene) to acetaldehyde. The reaction can be represented as follows: ``` CH2=CH2 + O3 → CH3CHO ``` This reaction results in the formation of acetaldehyde (CH3CHO) from ethene.
