Vedclass · Answer

(D) Ethers contain an oxygen atom with two lone pairs of electrons,which makes them act as weak Lewis bases. When ethers are dissolved in cold concentrated sulfuric acid $(H_2SO_4)$,the oxygen atom of the ether gets protonated by the acid to form an oxonium salt. The reaction is as follows: $R-O-R' + H_2SO_4 \rightarrow [R-O(H)-R']^+ HSO_4^-$ Here,the product formed is an oxonium salt.

Ethers,when dissolved in cold concentrated sulfuric acid,form:
