FAQs on Isomerism Video Lecture - Chemistry for JEE Main & Advanced

1. What is isomerism?
Ans. Isomerism is a phenomenon in chemistry where two or more compounds have the same molecular formula but different structural arrangements or spatial orientations, leading to distinct chemical and physical properties.
2. How does structural isomerism differ from stereoisomerism?
Ans. Structural isomerism refers to the situation where isomers have different connectivity or arrangement of atoms in their structures. On the other hand, stereoisomerism occurs when isomers have the same connectivity of atoms but differ in their spatial arrangement or orientation.
3. What are the two main types of stereoisomerism?
Ans. The two main types of stereoisomerism are geometric (cis-trans) isomerism and optical isomerism. Geometric isomerism arises when compounds have restricted rotation around double bonds, resulting in different spatial arrangements. Optical isomerism, also known as chirality, occurs when compounds possess a non-superimposable mirror image due to the presence of a chiral center.
4. What is the significance of isomerism in drug development?
Ans. Isomerism plays a crucial role in drug development as different isomers can have varying pharmacological activities and side effects. The specific arrangement of atoms can affect a drug's efficacy, toxicity, and interactions with biological targets. Therefore, understanding and controlling isomerism is essential in designing safe and effective drugs.
5. Can you provide an example of isomerism in everyday life?
Ans. One common example of isomerism in everyday life is found in glucose and fructose. Both glucose and fructose have the same molecular formula (C6H12O6), but they differ in their structural arrangement. Glucose is a primary source of energy for living organisms, while fructose is a naturally occurring sugar found in fruits and honey.
