Assertion : Dimethyl sulphoxide is commonly used for the reduction of an ozonide of an alkene to get the carbonyl compound. 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.
4 Assertion is incorrect but reason is correct.
Explanation:
Both assertion and reason are true and the reason is the correct explanation of the assertion.

Ozonolysis of \(\mathrm{C}_{7} \mathrm{H}_{14}\) gave 2-Methylpentan-3-one. The alkene is
1 2-ethyl-3-methylbut-1-ene
2 3-ethyl-2-methylbut-3-ene
3 2, 5-dimethyl-3, 4-dimethylhex-3-ene
4 3-ethyl-2-methylbut-1-ene
Explanation:
Since the ozonolysis product, 2-methyl-3-pentanone, contains only six carbon atoms, while the alkene has seven carbon atoms, the other ozonolysis product should be \(\mathrm{CH}_{2} \mathrm{O}\), the only carbonyl compound having one carbon atom. Hence, the structure of the alkene \(\mathrm{C}_{7} \mathrm{H}_{14}\) can be established as below.
