Chapter 7, Problem 11P

(a)

Interpretation Introduction

Interpretation:

The name of the following molecule should be determined.

  

Concept Introduction:

Compounds consist of carbon and hydrogen is known as hydrocarbons. Unsaturated hydrocarbon having double bond is known as alkene having general molecular formula ${\text{C}}_n{\text{H}}_{2n}$ . Unsaturated hydrocarbon having triple bond is known as alkyne having general formula ${\text{C}}_n{\text{H}}_{2n-2}$

Rules of naming alkenes are:

1. First choose the longest continuous chain of carbon atoms having double bond known as parent chain.
2. The numbering of parent chain should be done in a way that the double bond and substituents get the lowest number.
3. The root name of the carbon chain is same as in case of alkanes, but “−ane” ending is replaced by “−ene”
4. The appropriate name should be given to every alkyl group and denote its position on the parent chain with the number.
5. The alkyl groups are written in alphabetical order.

Rules of naming alkynes are:

1. First choose the longest continuous chain of carbon atoms having triple bond known as parent chain.

2. The numbering of parent chain should be done in a way that the triple bond and substituents get the lowest number.

3. The root name of the carbon chain is same as in case of alkanes, but “−ane” ending is replaced by “−yne”

4. The appropriate name should be given to every alkyl group and denote its position on the parent chain with the number.

5. The alkyl groups are written in alphabetical order.
