Chapter 11, Problem 11A.10E

(a)

Interpretation Introduction

Interpretation:

The systematic name of the compound ${\text{CH}}_{\text{3}}{\text{=CHCH}}_{\text{2}}\text{CH}\left({\text{C}}_{\text{6}}{\text{H}}_{\text{5}}\right){\left({\text{CH}}_{\text{2}}\right)}_{\text{4}}{\text{CH}}_{\text{3}}$ has to be given.

Concept Introduction:

Alkenes:  The simplest unsaturated hydrocarbon with a double bond is called as alkene.  The name of alkane ends with “-ene”.

Rules for naming compound:

1. 1) The carbon atoms in the longest chain have to be counted.
2. 2) The substituents and multiple bonds have to be identified and counted and the suffix “-ene” is added.
3. 3) The backbone carbon atoms have to be numbered by assigning the lowest number from the starting end that contains the double bond.

(b)

Interpretation Introduction

Interpretation:

The systematic name of the compound ${\text{CH}}_{\text{3}}\text{CHCH}\left({\text{CH}}_{\text{3}}\right)\text{CHClC}\equiv {\text{CCH}}_{\text{3}}$ has to be given.

Concept Introduction:

Alkynes:  Alkynes are hydrocarbons with one carbon-carbon triple bond.  The name of the alkyne ends with “-yne”.

Alkenes:  The simplest unsaturated hydrocarbon with a double bond is called as alkene.  The name of alkane ends with “-ene”.

Rules for naming compound:

1. 1) The carbon atoms in the longest chain have to be counted.
2. 2) The substituents and multiple bonds have to be identified and counted and the suffix “-yne” is added.
3. 3) The backbone carbon atoms have to be numbered by assigning the lowest number from the starting end that contains the double bond.
