Question

what is catenation and isomerism?

Answer 1

In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. A chain or a ring shape may be open if its ends are not bonded to each other, or closed if they are bonded in a ring.

In chemistry, isomers are ions or molecules with identical formulas but distinct structures. Isomers do not necessarily share similar properties. Two main forms of isomerism are structural isomerism and stereoisomerism. 

Answer 2

Explanation:

chemical and physical properties are called isomers the phenomena is called ISO marriage the difference in properties of this compound is due to the difference in the inner structure this compound have identical molecular formula but different structures hence they are called structural isomerism and phenomena is called structural isomerism structural isomerism are possible for butane similarly in some compounds carbon atoms are arranged in the form of rain for example cyclohexene and benzene
