Question

Ethyl cloride reacts with sodium ethoxide to form a compound (A)Which of the following reaction also yields (A) ?
A. `C_(2)H_(5)Cl, KOH"(alc.)", Delta`
B. `2C_(2)H_(5)OH," conc. "H_(2)SO_(4), 140^(@)C`
C. `C_(2)H_(5)Cl, Mg "(dry ether)"`
D. `C_(2)H_(2)," dil. "H_(2)SO_(4), HgSO_(4)`

Answer 1

Correct Answer - B
Ethyl chloride reacts with sodium ethoxide to form diethyl ether as
`C_(2)H_(5)Cl+NaOC_(2)H_(5) rarr underset("Diethyl ether")(C_(2)H_(5)-O-C_(2)H_(5))+NaCl`
Diethyl ether is also obtained by reaction of ethyl alcohol with conc. `H_(2)SO_(4)` at `140^(@)C`.
