Case Study Question 01
Chapter 4: Carbon and its Compounds
Read the following passage carefully and answer the following questions:
The compounds which have the same molecular formula but differ from each other in physical or chemical properties are called isomers and this phenomenon is known as isomerism. Structural isomerism is when isomers have difference in the arrangement of atoms within the molecule, without any reference to space. We can say that compounds which have the same molecular formula but different structural formula show structural isomerism. Compounds of carbon show this phenomenon as the atoms can be linked together in the form of straight chains, branched chains or even rings.
Among the following sets of compounds, choose the set having thesame molecular formulae:
(a) Butane and iso-butane
(b) Cyclohexane and hexene
(b) Propanal and propanone
