Which statement is correct about the following reactions ?
.

Options

A. Product is by elimination reaction.
B. Product is by substitution reaction.
C. Both (a) and (b)
D. None

Answer

A

Explanation

`3^@ RX` and `1^@` alkoxide ions give elimination reaction whereas `1^@ RX` and `3^@` alkoxide ions undergo `SN^2` reaction (Williamson's synthesis). Alternatively, nucleophile `(MeO^(Ө))` cannot attack `3^@ C` atom having high `overline e` density hence elimination occurs to give alkene.
