Draw an alcohol and an alkyl bromide that could be combined to give the ether shown.

See explanation

Explanation:

The question is incomplete, however, I found an example of this question on another site, so, I'm going to explain to you how to do it basing on this example, and then, apply it in your case. In the picture 1, is the example, and picture 2 is the solution.

Now, this type of reaction is known as the "Williamson Ether synthesis" and the overall of this, is a reaction that involves an alkoxyde ion with an primary alkyl halide like this:

RO- + R'X ------> ROR' + X-

This is a Sn2 reaction, and it's really fast.

Following the example in picture 1, the result is in picture 2. Hope this can help you.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
