Organic Chemistry Chapter 2 Exam
Questions with Correct Answers
Alkanes - ANSWER: entirely single bonds between carbons and hydrogens
Alkenes - ANSWER: has a double bond and sp2 hybridization between some C and
hydrogens
Alkynes - ANSWER: has a triple bond between some carbon and hydrogens, sp
hybridized
What is the difference between benzene aromatic compound and toluene compound? -
ANSWER: Toluene has a methyl added to one of the Carbons in the ring
What determines a dipole moment? - ANSWER: It is determined by the magnitude and
direction of the individual bond dipole moments. It is determined by vector quantities.
True or False, Cis and Trans isomers have the same dipole moments? - ANSWER:
False, they have different physical properties including their dipole moments
What do functional groups typically contain? - ANSWER: They typically contain multiple
bonds, unshared pairs of electrons, and non-carbon atoms
-usually where the reaction take place

What is a primary carbon haloalkane? - ANSWER: It is an alkyl halide with the "R"
group and two "H"s on the carbon baring the halo-atom
What is a secondary carbon haloalkane? - ANSWER: It is an alkyl halide with two "R"
groups and one "H" attached to the halo-atom bearing carbon
What is a tertiary carbon haloalkane? - ANSWER: It is an alkyl halide with three "R"
groups and no "H"s attached to the halo-atom bearing carbon
What is the functional group in an Alkyl Halide? - ANSWER: The functional group is a
halogen attached to a Carbon.
