Chapter 21.2, Problem 9PP

Interpretation Introduction

Interpretation:

The structure of 2, 3-dimethyl-5-propyldecane needs to be drawn.

Concept introduction:

The hydrocarbon compounds that contains single bond(s) between carbon atom(s) are said to be saturated hydrocarbon. Hydrocarbon compounds containing single bonds only are said to be alkane.

Answer to Problem 9PP

Explanation of Solution

Alkanes are compounds containing carbon and hydrogen atoms having single bond(s) between carbon atom(s) in the structure. For number of carbons atoms in alkane chain, the prefix is given as:

The numbering of the carbon chain is done in such a way that substituents gets lower number.

The given name is 2, 3-dimethyl-5-propyldecane that means the parent chain has 10 number of carbons in the chain and -dimethyl represents the presence of two methyl substituents at position 2 and 3 and -propyl substituent at position 5. So, the structure of 2, 3-dimethyl-5-propyldecane is:

Interpretation Introduction

Interpretation:

The structure of 3, 4, 5-triethyloctane needs to be drawn.

Concept introduction:

The hydrocarbon compounds that contains single bond(s) between carbon atom(s) are said to be saturated hydrocarbon. Hydrocarbon compounds containing single bonds only are said to be alkane.

Answer to Problem 9PP

Explanation of Solution

The given name is 3, 4, 5-triethyloctane that means the parent chain has 8 number of carbons in the chain and -triethyl represents the presence of three ethyl substituents at position 3, 4 and 5. So, the structure of 3, 4, 5-triethyloctane is:
