Question
Chapter 4, Problem 4.5P
Interpretation Introduction
(a)
Interpretation: The identical compounds (B-F) to A are to be identified.
Concept introduction: The acyclic hydrocarbons are open chain hydrocarbons. One can represent there skeletal structure in different ways. They may be same or different. The same skeletal structures are identical to each other in terms of physical and chemical properties.
Interpretation Introduction
(b)
Interpretation: The compounds (B-F) that represent an isomer of A are to be identified.
Concept introduction: Isomers are the compounds that have same molecular formula, but possess different skeletal structures. They differ to each other in terms of physical and chemical properties.
