A spontaneous flow of thermal energy takes place from hot to cold. In order to flow thermal energy from a colder object to a hotter object, the work has to be implied on the system. The particle at higher temperature exhibits more kinetic energy in comparison to the particle at a lower temperature. Thus, there is a continuous flow of heat between the objects from the higher temperature to the lower temperature.
The 2,4 and 5 positions are accessible for nitration of 1,3‑dimethylbenzene. The final product is shown in the image attached.
<h3>What is nitration?</h3>
Nitration is a type of reaction in which the nitro group (-NO2) is introduced to an aromatic ring. We have to note that in the compound 1,3‑dimethylbenzene, the 2,4 and 5 positions are accessible for nitration as shown.
Hence, the nitration of 1,3‑dimethylbenzene occurs as shown in the image attached with the compound shown being the major product.
