WebIn these reactions a phenoxide ion displaces a halide ion from a primary haloalkane. Because alcohols are weak acids, an alkoxide ion must be prepared using a strong base such as sodium hydride. However, phenols are much more acidic than alcohols, so phenoxides can be obtained by adding hydroxide ion to the phenol.
