Chapter 20, Problem 137AP
Interpretation Introduction

Interpretation:

The structural formula for 2-propanol should be drawn and whether it is primary, secondary, or tertiary alcohol should be indicated.

Concept Introduction:

The formula in which the arrangements of atoms in a molecule are shown is said to be the structural formula.

  • An organic compound in which hydroxyl functional group that is -OH is bonded to the carbon atom is said to be an alcohol. The general formula for alcohol is Cn H2 n + 1 OH. Based on the attachment to the carbon the alcohols are classified as primary, secondary, or tertiary alcohol.
  • When alcohol (having hydroxyl group) is attached to a primary carbon atom (carbon atom to which one carbon atom is attached) then such alcohol is said to be a primary alcohol.

When alcohol (having hydroxyl group) is attached to a secondary carbon atom (carbon atom to which two carbon atoms are attached) then such alcohol is said to be a secondary alcohol.

When alcohol (having hydroxyl group) is attached to a tertiary carbon atom (carbon atom to which three carbon atoms are attached) then such alcohol is said to be a tertiary alcohol.

Answer to Problem 137AP

Introductory Chemistry: A Foundation, Chapter 20, Problem 137AP , additional homework tip  1

Secondary alcohol.

Explanation of Solution

For number of carbons atoms in chain, the prefix is given as:

Carbon-1     meth

Carbon-2    eth

Carbon-3    prop

Carbon-4     but

Carbon-5     pent

Carbon-6    hex

Carbon-7     hept

Carbon-8     oct

Carbon-9     non

Carbon-10     dec

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

The given name is 2-propanol that means the parent chain has 3 number of carbons in the chain and suffix -ol represents it is an alcohol group that is R-OH (where R is alkane/alkyl group) at 2 position. So, the structural formula of 2-propanol is:

Introductory Chemistry: A Foundation, Chapter 20, Problem 137AP , additional homework tip  2

Since, -OH is attached to secondary carbon so, it is a secondary alcohol.

Interpretation Introduction

Interpretation:

The structural formula for 2-methyl-2-propanol should be drawn and whether it is primary, secondary, or tertiary alcohol should be indicated.

Tertiary alcohol.

Explanation of Solution

For number of carbons atoms in chain, the prefix is given as:

Carbon-1     meth

Carbon-2    eth

Carbon-3    prop

Carbon-4     but

Carbon-5     pent

Carbon-6    hex

Carbon-7     hept

Carbon-8     oct

Carbon-9     non

Carbon-10     dec

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

The given name is 2-methyl-2-propanol that means the parent chain has 3 number of carbons in the chain and suffix -ol represents it is an alcohol group that is R-OH (where R is aryl/alkyl group) at 2 position, and a methyl substitution at 2 position. So, the structural formula of 2-methyl-2-propanol is:

Introductory Chemistry: A Foundation, Chapter 20, Problem 137AP , additional homework tip  4

Since, -OH is attached to tertiary carbon so, it is a tertiary alcohol.

Interpretation Introduction

Interpretation:

The structural formula for 4-isopropyl-2-heptanol should be drawn and whether the it is primary, secondary, or tertiary alcohol should be indicated.

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

The given name is 4-isopropyl-2-heptanol that means the parent chain has 7 number of carbons in the chain and suffix -ol represents it is an alcohol group that is R-OH (where R is aryl/alkyl group) at 2 position, and anisopropyl substitution at 4 position. So, the structural formula of 4-isopropyl-2-heptanol is:

Introductory Chemistry: A Foundation, Chapter 20, Problem 137AP , additional homework tip  6

Since, -OH is attached to secondary carbon so, it is a secondary alcohol.

Interpretation Introduction

Interpretation:

The structural formula for 2, 3-dichloro-1-pentanol should be drawn and whether the it is primary, secondary, or tertiary alcohol should be indicated.
