2-Methyloxirane (propylene oxide) is treated with $CH X_{3} ONa$ in methanol (basic conditions), then work-up. The major product is

Under basic conditions the nucleophile

CH X_{3} O X^{-}

attacks the less hindered ring carbon (the

CH X_{2}

) by SN2. This gives

CH X_{3} O - CH X_{2} - CH (OH) - CH X_{3}

after protonation, 1-methoxypropan-2-ol.
