Provide a detailed, stepwise mechanism for the acid-catalyzed reaction of 2-butanone with ethylene glycol (HOCH2CH2OH) to produce an acetal.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

d.) circle motion requires a force to give it a centripetal acceleration.

where are the choice options?

lol for the pointsss
