Answer»

Mixing EtONa with `Me_(3)C CL`
Mixing `Me_(3)CONa` with EtCl
heating a mixture of (1:1) EtOH and `Me_(3)COH` in presence of conc. `H_(2)SO_(4)`
Treatment of `Me_(3)COH` withh EtMgI

Solution :`CH_(3)-underset(CH_(3))underset(|)OVERSET(CH_(3))overset(|)(C)-OVERLINE(O)Naoverset(+)(a)+CH_(3)CH_(2)Cl overset(S_(N^(2))toCH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-O-CH_(2)CH_(3)+NaCl`
