Question

1. What is metamerism? Give example for metamers. 

2. What are free radicals? How are they formed?

Answer 1

1. It is the isomerism which arises due to different alkyl chains on either side of the functional group in the molecule.

e.g. Methoxy propane(CH₃OC₃H₇) and ethoxyethane (C₂H₅OC₂H₅) are metamers.

2. Free radicals are highly reactive species containing unpaired electrons. They are formed by homolytic cleavage of covalent bond.

e.g. H₃
