Question

What are isomers ? Why can’t we have isomers of first three members of alkane series ? Draw the possible structures of isomers of butane, C4H10.

Answer 1

1. organic compounds with same molecular formula but different chemical and structural formula are known as isomers. This phenomena is known as isomerism.

2. this is because,branching is not possible in only three carbon atoms. everytime we'll arrange these three carbon atoms the ,the arrangement will be same.

3. There are only two possible structural isomers of butane namely, ISOBUTANE (double chain)and NORMALBUTANE( single chain)

Thank u

Answer 2

Isomers:

Isomers are the elements, of the identical molecular formula, however one-of-a-kind structural formulas. They have some formulas, however, their form is one-of-a-kind.

Isomers of the first three members of alkane as:

• We can’t we have got were given isomers for the number one three members of alkane because of the reality they've got the same structural formula.
• If we skip via the definition of isomers, there are factors with the equal molecular formula but are not viable from the number one or the very last carbon atom of the structure, but extraordinary structural formulas.
• Moreover, isomerism isn't viable withinside the number one three alkanes typically due to the fact of branching.
• Additionally, the figure chain has the most effective 1, 2, and three carbon atoms so it isn't feasible to have distinct preparations of carbon (C) atoms.
