Question

The branch of chemistry that deals with the structure of matter, the energy changes and the theories, laws and principles that explain the transformation of matter from one form to another is called _____ chemistry
A. Inorganic chemistry
B. Organic chemistry
C. Analytical chemistry
D. Physical chemistry

Answer 1

Hint: This branch of chemistry also helps in studying the nature of matter. This branch also deals with the behavior of matter at a molecular level. That is, it helps in understanding the position and movement of matter in space when exposed to different conditions.

Complete answer:
Let us first understand each option one by one :
Physical chemistry is a branch of chemistry that helps in understanding the interaction of matter with each other in terms of intermolecular forces found between them. It can be used to measure the rate of a reaction that is occurring. It can also be used in finding the internal energy of a system. In addition to the internal energy, it can also be used to find some energy parameters attributed to a system or its surroundings like heat, entropy and so on.
Organic chemistry is the branch of chemistry that deals with carbon and the compounds formed from carbon. For example, it is the study of the different properties like the tetravalency of carbon, catenation in carbon, and so on.
Analytical chemistry can be defined as the branch that deals with the measurement of matter. It is the process of obtaining and processing information about matter.
Inorganic chemistry is the study of properties and interaction between inorganic compounds like sulphur, calcium and others. Any compound formed from elements other than carbon is an inorganic compound.
From the above information, we will realize that the answer to the question is option d that is Physical Chemistry.

So, the correct answer is “Option D”.

Note:
Physical chemistry can be used to measure the time of a reaction and the energy associated with a reaction. It is a medium through which the equilibrium of a reaction can be found. It helps in understanding the interaction of matter with each other in terms of intermolecular forces found between them
