CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS

323818 Assertion :
Dimethylsulphide is commonly used for the reduction of an ozonide of an alkene to get the carbonyl compounds.
Reason :
It reduces the ozonide giving water soluble dimethyl sulphoxide and excess of it evaporates.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
