Sometimes explosion occurs while distilling ethers. It is due to the presence of
1 peroxides
2 oxides
3 ketones
4 aldehydes.
Explanation:
In the presence of air and light, ethers form peroxides which cause explosion during distillation.

Assertion : Ethers can be dried by using sodium wire. Reason : Ethers do not react with sodium.
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:
Sodium wire efficiently dries ethers by reacting with water impurities to form sodium hydroxide, eliminating moisture and ensuring a dry solvent. So the option (1) is correct.
