LAB: Constructing molecular models of organic compounds (include title on your lab report)
PURPOSE: To practice visualizing and drawing structures for many organic compounds (include purpose as well)
PROCEDURE: Construct molecular models for each of following organic compounds. After constructing the model,
write its name and then draw a picture of it in your lab report, and write its formula. Also, answer relevant questions
which appear below in your lab report.
PART I
1) Pentane
2) 2-methylbutane
3) 2,2-dimethylpropane
In your lab report: What is significant about structures 1-3? Which one would have the highest boiling point?
Why?
4)
5)
6)
7)
8)
3-ethylhexane
cyclopentane
1,2-dichlorocyclohexane
2-bromo-4-iodo-1-butene
4,4-dimethyl-2-pentyne
Hint: for #’s 9-12, see margin note on page 1033 of your textbook.
9) cis-2-pentene
10) trans-2-pentene
11) cis-1,2-dichloroethene
12) trans-1,2-dichloroethene
In your lab report:
Explain the difference between cis and trans alkenes.
Why do cis and trans isomers not exist for alkanes?
Why do cis and trans isomers not exist for alkynes?
PART II
Use your textbook and workbook to create models for #’s 13-26
13) 3-pentanol
14) 2,2-dimethyl-1-pentanol
15) butanoic acid
16) 3-methylbutanoic acid
17) hexanal
18) 2,3-dimethylhexanal
19) 2-pentanone
20) 3-ethyl-2-pentanone
21) methyl butanoate
22) ethyl 4-methylpentanoate
23) 2-ethoxybutane
24) 1-chloro-2-methoxyethane
25) 2-chloro-1-butanamine
26) 2-methylcyclobutanamine
27) propanamide
28) 2-methylbutanamide
In your lab report: label #’s 13-28 as one of the following:
ALCOHOL, ETHER, ESTER, ALDEHYDE, KETONE, CARBOXYLIC ACID, AMINE. AMIDE
In your lab report: Create a table which summarizes the system used for naming each of the following:
ALCOHOL, ETHER, ESTER, ALDEHYDE, KETONE, CARBOXYLIC ACID, AMINE, AMIDE
PART II
Use your textbook and workbook to create models for #’s 13-26
13) 3-pentanol
14) 2,2-dimethyl-1-pentanol
15) butnaoic acid
16) 3-methylbutanoic acid
17) hexanal
18) 3,4-dimethylhexanal
19) 2-pentanone
20) 3-ethyl-2- pentanone
21) methyl butanoate
22) ethyl pentanoate
23) 2-methoxybutane
24) ethoxyethane
25) methanamine
26) cyclobutanamine
In your lab report: Use the chart on page 1052 of your textbook in order to label #’s 13-26 as one of the following:
ALCOHOL, ETHER, ESTER, ALDEHYDE, KETONE, CARBOXYLIC ACID, AMINE.
In your lab report: Write a brief description of the process used for naming each of the following: ALCOHOL,
ETHER, ESTER, ALDEHYDE, KETONE, CARBOXYLIC ACID, AMINE.
