The compound that ontains the most deactivated aromatic ring is the one called Nitrogen dioxide also knwon as NO2. Let me explain a little bit more about the aromatic rings. These rings are simple aromatics, or arenes, that consist of a conjugated planar ring system. Nitrogen generally is a simple aromatic ring that can be heterocyclic because containsnon-carbon ring atoms. The rings of the nitrogen can be separated into basic aromatic rings and that is why this ompound is also refered as a deactivated aromatic ring.
Answer: Option (d) is the correct answer.
Explanation:
When heat is removed from water then there will be decrease in the kinetic energy of water particles. This is because on removing the heat, collisions between the particles will decrease as a result the energy will decrease. Thus, particles will stop moving randomly from one place to another.
Therefore, kinetic energy of the water particles decreases.
