Question

Click the "draw structure" button to launch the drawing utility. Draw the product of the reaction of propanal with lithium aluminum hydride, followed by water.

Answer 1

Answer:

Product: propan-1-ol

Explanation:

IIn this case, we have to remember that $LiAlH_4$  is a reduction agent.  So, this is a reduction reaction. The $LiAlH_4$ has the ability to produce hydride ions $H^-$. This ion can attack the carbonyl group generating a negative charge in the oxygen. In the next step, the negative charge in the oxygen can attack a water molecule to protonate the molecule and produce propan-1-ol.

See figure 1

I hope it helps!
