Answer: By using LAH in the presence of ether.
Explanation:
We are given an organic compound named as but-2-en-1-al and we need to convert it into but-2-en-1-ol. Aldehyde gets converted into alcohol by undergoing reduction reaction.
Reduction of the given aldehyde is carries out in the presence of LAH/ether. Ether is used because otherwise LAH is a strong reducing agent but in the presence of ether, it is not very good at reducing alkenes.
The equation for this is provided in the image below.
