Chapter 11, Problem 11A.9E

(a)

Interpretation Introduction

Interpretation:

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

Concept Introduction:

Alkanes:  Saturated hydrocarbons are called as alkanes.  Each atom in an alkane shows the presence of four single bonds in a tetrahedral arrangement with ${\text{sp}}^{\text{3}}$ hybridization.  The name of alkane ends with “-ane”.

Rules for naming compound:

1. 1) The carbon atoms in the longest chain have to be counted.
2. 2) The substituents have to be identified and counted.
3. 3) The backbone carbon atoms have to be numbered by assigning the lowest number from the starting end.
