Ether in contact with air for a long time form peroxides. The presence of peroxide in ether can be tested by adding \(\mathrm{Fe}^{2+}\) ion in it and then adding
1 \(\mathrm{KSCN}\)
2 \(\mathrm{SnCl}_{2}\)
3 \(\mathrm{HgCl}_{2}\)
4 \(\mathrm{KI}\)
Explanation:
Peroxides oxidises \({\text{F}}{{\text{e}}^{{\text{2 + }}}}\) to \({\text{F}}{{\text{e}}^{{\text{3 + }}}}\) which gives red colur with KSCN

Assertion : Etherates are coordination complexes of ethers with Lewis acids. Reason : Ethers are easily cleaved by mineral acids such as \(\mathrm{HCl}\) and \(\mathrm{H}_{2} \mathrm{SO}_{4}\) at \(373 \mathrm{~K}\).
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:
Ethers, act as Lewis bases. Ethers, with their lone pairs of electrons on the oxygen atom, can readily donate electron pairs to Lewis acids. When they interact with Lewis acids, the resulting complexes are commonly referred to as "ethers" or "etherates." Ethers are not easily cleaved by sulphuric acid or \(\mathrm{HCl}\). Thus assertion is true but reason is false. So the option (3) is correct.
