What is the acetal formed when propanone reacts with two molecules of methanol?

2,2-dimethoxypropane.

Explanation:

Hello,

At first, acetals are organic molecules with a central carbon atom that has four bonds joined to it, and is therefore saturated with a tetrahedral geometry. Acetals come from the reaction between a ketone and two molecules of alcohol to promote the carbonyl break and the subsequent replacement by two alkoxy radicals.

In this case, when propanone reacts with two moles of propanol, 2,2-dimethoxypropane is produced via the break of the carbonyl group and the subsequent replacement by two methoxy radicals. This is shown on the attached picture.

Best regards.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
