(acetone) has a molecular ion at m/z = 58, an infra red absorption at 1650cm^-1
Acetone is a synthetic substance that is also naturally present in the environment. It is a tasteless, colourless liquid with a distinct odour. It is combustible, readily evaporates, and dissolves in water. It is also known as beta-ketopropane, 2-propanone, and dimethyl ketone. Plastic, fibres, medications, and other compounds are all made from acetone.
Other substances can also be dissolved with it. It is a byproduct of the breakdown of human fat and is found naturally in plants, trees, volcanic gases, forest fires, and other organisms. It can be found in landfills, tobacco smoke, and automobile exhaust. Acetone is released into the environment more through industrial processes than through natural ones.

<u>Answer:</u> The given statement is true.
<u>Explanation:</u>
For the reaction to be spontaneous, the Gibbs free energy of the reaction must come out to be negative.
The equation used to calculate Gibbs free energy follows:
Exothermic reactions are defined as the reactions in which energy is released in the form of heat. The enthalpy change of the reaction comes out to be negative for this kind of reaction.
Entropy change is defined as the change in the measure of randomness in the reaction. It is represented as . Randomness of gaseous particles is more than that of liquid which is further more than that of solids.
We are given:
A solid substance is converting into a gaseous substance.
As, the entropy is increasing. So, the entropy change is positive.
Thus, the above reaction is spontaneous.
Hence, the given statement is true.
