Question

What is meant by isomers ? "We cannot have isomers of first three members of alkane series".Give reason to justify this statement.Draw the structures of two isomers of pentane C5H12

Answer 1

See the attached file for solution. Thanks

Answer 2

Answer:

Isomers are chemical compounds that have an identical formula but the arrangement of atoms in a molecule is different and they also have different properties.

Explanation: The 2 main types of isomerism are structural isomerism and stereoisomerism.

• Structural isomerism is further divided into positional, chain isomerism, functional, metamerism, tautomerism, and ring-chain.

• Stereoisomerism is further divided into geometric and optical isomerism.

• We cannot have isomers of the first three members of the alkane series because there is no possibility of brachiation from the first or last carbon atom of the structure, without the formation of branches to form different structures, isomerism is not possible.
• Structures of isomers of pentane C5H12 in a picture are attached below.
