(a) Give two syntheses for (CH 3 ) 2 CH−O−CH 2 CH 3 , and explain which synthesis is better.

(a) Give two syntheses for (CH₃)₂CH−O−CH₂CH₃, and explain which synthesis is better.

(b) A student wanted to synthesize methyl tert-butyl ether, CH₃−O−C(CH₃)₃. He attempted the synthesis by adding sodium methoxide (CH₃ONa)to tert-butyl chloride, but he obtained none of the desired product. Show what product is formed in this reaction, and give a better synthesis for methyl tert-butyl ether.
