Question diagram
A

CH3OH , H2SO4\text{CH}_3\text{OH}\ , \ \text{H}_2\text{SO}_4

B

CH3OH , CH3ONa+\text{CH}_3\text{OH}\ , \ \text{CH}_3\text{O}^-\text{Na}^+

C

H2/ H2SO4\text{H}_2\text{O}\ /\ \text{H}_2\text{SO}_4 followed by CH3OH\text{CH}_3\text{OH}

D

CH3MgBr / ether\text{CH}_3\text{MgBr}\ /\ \text{ether} followed by H3O+\text{H}_3\text{O}^+

Correct Answer

Option A

Detailed Explanation

The reaction sequence involves the dehydration of an alcohol (CH₃CH₂OH) using H₂SO₄, leading to the formation of an alkene intermediate, which can then undergo further reactions. The presence of CH₃OH suggests that a methyl ether might form, but the final product is a compound with an ether linkage (HOCH₂-CH⁻CH₃) and an alkoxy group (OCH₃). Other options are not applicable as they do not represent valid products formed from the given reactants and conditions. Understanding the mechanisms of dehydration and ether formation is crucial in organic chemistry for predicting reaction outcomes.
