Answer 1

Ans:

Please find the attached image.

1. For question 2&3 procedure: structure 1 and 2 (in image). Only two isomers possible with the branching of -CH₃

2. For question 4 procedure: structures 1 to 8 (in image)

3. For question 2 analyze and conclude: structure 8 (butane is the shortest chain)

4. Each structural isomers has a unique name owing to the IUPAC nomenclature rules. It states that, identify the longest C chain as a parent chain, then give numbering to the substituents on the parent chain in an alphabetical order such that they get the lowest possible position number.
