Ochem 1 Final ACS Exam
Comprehensive Questions
(Frequently Tested) with
Verified Answers Graded A+
what is the trend for radical stability - Answer: the same as carbocation stability;
tertiary>secondary>primary
for most contributing resonance structure, where do we want the positive charge - Answer: it is
better for the positive to be on a noncarbon atom so that a carbocation is not formed
what are the shapes of each hybridization - Answer: sp is linear, sp2 is trigonal planar, and sp3 is
tetrahedral
what is the shape of an oxygen with 2 lone pairs - Answer: bent
learn the combinations of the ____ ____ ____ ____ for each hybridization - Answer: look in
textbook!
what is an aryl halide - Answer: halogen bonded to an aromatic ring
in water, which carbon chain with an alcohol is the most soluble - Answer: the one with the
smallest R chain
, what functional group is in a peptide bond - Answer: amide
what is the geometry of 2 bonds 1 lone pair - Answer: bent
what is the geometry of 3 bonds 1 lone pair - Answer: trigonal pyramid
what is the geometry of 2 bonds 2 lone pairs - Answer: bent
what is a lewis acid - Answer: electron pair acceptor
what is a lewis base - Answer: electron pair donator
what is a bronsted acid - Answer: H donator
what is a bronsted base - Answer: H acceptor
are all bronsted acids lewis acids - Answer: yes
are all lewis acids bronsted acids - Answer: no
which is the most acidic proton - Answer: Acidic protons are usually bound to O or N; compare
functional groups and pkas because the most acidic proton will be in the most acidic functional
group; when comparing the same functional group, subsituients add to acidity
what is a nucleophile - Answer: electron rich
