UNCG CHEM 104 EXAM 2 QUESTIONS
AND ANSWERS
the intramolecular dehydration of 2-penanol produces? - Answer-2-pentene
The common name of CH3-CH2-O-CH2-CH3 is - Answer-diethyl ether
in the IUPAC naming system, a ketone is named by replacing the -e in the
corresponding alkane name with? - Answer--one
R-S-S-R - Answer-disulfide
What is BHT used as? - Answer-commercial phenolic antioxidant food additive
the addition of hydrogen to an organic compound or the loss of oxygen is called -
Answer-reduction
Thiols have structures similar to alcohols except that they contain - Answer-sulfur in
place of oxygen in the functional goup
Tertiary alcohols cannot be oxidized because - Answer-the alcohol carbon is bonded
to four groups so no oxygen can be added to it
When a primary alcohol is completely oxidized, the product is - Answer-a carboxylic
acid
Thiols can be gently oxidized to - Answer-disulfides
what is a three -OH groups bonded to 3 different carbons, which is a clear, thick
liquid with the consistency of honey and is natures antifreeze? - Answer-glycerol
what is the IUPAC name of the aldehyde whose common name is formaldehyde -
Answer-methanal
in IUPAC nomenclature, which one of the functional groups has the highest priority?
- Answer-carboxylic acid
match the following structural formula with the compound types in the response list
CH3-CH2-SH - Answer-thiol
Hydrolysis of an acetal in an acid solution would yield - Answer-an aldehyde or a
ketone and two alcohols
two other acceptable names for the molecules acetone are - Answer-propanone and
dimethyl ketone
what type of reaction is this? R1-OH + R2-OH --> R1-O-R2 + H2O - Answer-
intermolecular alcohol dehydration
