Concept explainers
(a)
Interpretation:
Condensed structural formula for the given set of compounds has to be written.
Concept Introduction:
Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). IUPAC name consists of three parts in major namely Prefix suffix and root word.
Prefix represents the substituent present in the molecule and its position in the root name.
Suffix denotes the presence of
Root word represents the longest continuous carbon skeleton of the organic molecule.
The structure of a molecule can be drawn by analyzing the presence of prefix, suffix and root word in the given IUPAC name.
Condensed structural formula is representation of the organic compound. In this the lengthy carbon chain is shown only with the carbon atoms (along with the hydrogen) without any bonds. The additional branches are shown with explicit bonds.
To Write: The condensed structural formula for the given compounds.

Answer to Problem 23.39QP
The condensed structural formula for 2,5-dimethyloctane is,
Explanation of Solution
From the given name of the hydrocarbon, the parent carbon is identified as octane. Octane has eight carbon chain. In the given name it is given as two methyl groups are substituted in second and fifth carbon atom resulting in the skeleton of the hydrocarbon.
Remove the single bonds in the lengthy chain to obtain the condensed structural formula.

You DO NOT need to use the same number of arrows that are shown (you may use more or less), but the product must be formed from the reactant. Then write the mechanism of one step in the synthesis (you can choose which step to write the mechanism for), including all reagents required, clearly labeling the nucleophile and electrophile for each step, and using curved arrows to show the steps in the mechanism. a. b.
