Ethers are prepared by the reaction of sodium alkoxides and alkyl halides. Which of the following reagents should be taken to prepare methyl ter0-butyl ether?

A

(CH3)3CBr+NaOCH3\left( \mathrm { CH } _ { 3 } \right) _ { 3 } \mathrm { C } - \mathrm { Br } + \mathrm { NaOCH } _ { 3 }

B

CH3Br+NaOC(cH3)3\mathrm { CH } _ { 3 } \mathrm { Br } + \mathrm { NaOC } \left( \mathrm { cH } _ { 3 } \right) _ { 3 }

C

CH3CH2Br+NaOC(CH3)2\mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { Br } + \mathrm { NaOC } \left( \mathrm { CH } _ { 3 } \right) _ { 2 }

D

(CH3)2CBr+NaOCH2CH3\left( \mathrm { CH } _ { 3 } \right) _ { 2 } \mathrm { C } - \mathrm { Br } + \mathrm { NaOCH } _ { 2 } \mathrm { CH } _ { 3 }

Answer

CH3Br+NaOC(cH3)3\mathrm { CH } _ { 3 } \mathrm { Br } + \mathrm { NaOC } \left( \mathrm { cH } _ { 3 } \right) _ { 3 }

Explanation

Solution

Tertiary halide can involve elimination of HX to give alkene in presence a base hence a tertiary alkoxide and primary alkyl halide is taken for the reaction.
