Answer to Problem 32PP

Answer

The systematic names for the given molecules (a-c) are shown below.

(a). 2,2,5-Trimethyl-3-hexene

Explanation of Solution

The systematic name for the given molecule (a).

Draw the given molecule (a) and find the longest parent carbon chain or carbon skeleton and the substituents for naming the compound.

Organic Chemistry, Chapter 9, Problem 32PP , additional homework tip 1

(a). 2,2,5-Trimethyl-3-hexene

The given molecule is drawn. The parent carbon skeleton is the longest continuous carbon chain that should contain more number of carbons. In the given molecule the parent carbon skeleton is the chain which contains 6 carbons. Hence the root name of the molecule is hexa. Since it is an alkyne with 6 carbons then hexane will be the parent carbon chain name.

The substituents present in the molecule are methyl, bromo (Br) groups on 2 and 5. Therefore on numbering the three methyl groups are present at 2 and 5. Positions is 2,2,5-Trimethyl.

Hence the systematic name for the molecule (a) is 2,2,5-Trimethyl-3-hexene

Explanation of Solution

The systematic name for the given structure (d).

Draw the given molecule (d) and find the longest parent carbon chain or carbon skeleton and the substituents for naming the compound.

Organic Chemistry, Chapter 9, Problem 32PP , additional homework tip 4

3-Bromo-3-methyl-1-butyne

The given molecule is drawn. The parent carbon skeleton is the continuous carbon chain that should contain more number of carbons. In the given molecule the parent carbon skeleton is the chain which contains 4 carbons. Hence the root name of the molecule is butane. Since it is an alkene with 4 carbons then butyne will be the parent carbon chain name.

In the given molecule parent chain is numbered so that the triple bond assigned the lowest possible locate (1 indicates that the triple bond is located between C₁ and C₂). The one methyl group, one bromo groups are present at C₃ positions is 3-Bromo-3-methyl (The alphabetized in the name, Br and CH₃).

Hence the systematic name for the molecule (a) is 3-Bromo-3-methyl-1-butyne.

(a)

Interpretation Introduction

Interpretation:

The systematic name and IUPAC name of each group substituent in the given molecules should be identified.

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 functional group if any in the molecule. It can be an alkene, alkyne, alcohol, carboxylic acid, alcohol etc...

For alkynes molecules, suffix will be ‘yne’.

Root word represents the longest continuous carbon skeleton of the organic molecule.

Two stereoisomers are there for an alkyne molecule. It depends upon the location of bulky group (or high molecular weight) on the triple bonded carbon atoms. If the bulky groups are in same side then it is cis-isomer. If the bulky groups are in opposite side then it is trans-isomer.

(a). 2,2,5-Trimethyl-3-hexene

The given molecule is drawn. The parent carbon skeleton is the longest continuous carbon chain that should contain more number of carbons. In the given molecule the parent carbon skeleton is the chain which contains 6 carbons. Hence the root name of the molecule is hexa. Since it is an alkyne with 6 carbons then hexane will be the parent carbon chain name.

The substituents present in the molecule are methyl, bromo (Br) groups on 2 and 5. Therefore on numbering the three methyl groups are present at 2 and 5. Positions is 2,2,5-Trimethyl.

Hence the systematic name for the molecule (a) is 2,2,5-Trimethyl-3-hexene
