UPDATE 2026/2027 | VERIFIED.
In oxidative addition products of alkenes and alkynes, which reagents can be used?
Cold, alkaline permanganate, osmium tetroxide and proxy acids.
How are reductions of carbonyl compounds usually done?
complex metal hydrides
How are reductions of alkenes usually done?
Catalytic hydrogenation
How are reductions of alkynes usually done?
Catalytic hydrogenation or alkali metals in ammonia (dissolving metal reductions)
,ACS ORGANIC CHEMISTRY FINAL EXAM 2025
What are the two types of free-radical reactions? substitution and
addition.
What is the IUPAC priority for naming?
Carboxylic acid > Ketone > Aldehyde > Alcohol
In IUPAC naming, what is the suffix used for ketone groups?
-one
In IUPAC naming, what is the suffix used for alcohol groups?
-nol
In IUPAC naming, what is the suffix used for esters?
-noate
Benzyl group
Phenyl group
ethanoic acid
,(E) isomers vs. (Z) isomers. Which one is observed when the higher ranked
molecules are on the same side? opposite?
highest on same side: Z highest
on opposite sides: E
Electronwithdrawing groups are
what type of directors? What is
the one and only exception?
Meta (deactivators)
Halogens
What can react with alcohols to produce a ketone?
PCC (converts primary alcohols to aldehydes and secondary alcohols to ketones;
doesn't affect C=C bonds.
Chromic acid is an oxidizing reagent that does not oxidize ketones;
but it can oxidize C-C double bonds.
What can react with secondary alcohols to give ketones?
KMnO4, NaOH. But it can also react with double bonds.
, ACS ORGANIC CHEMISTRY FINAL EXAM 2025
If the atom directly attached to the aromatic ring has lone pairs what type of
director is it? what if it does not have lone pairs?
lone pairs: activating, ortho, para director no lone
pairs: deactivating, meta director
If there is a NO2 group present, what IUPAC prefix will also be evident?
nitro
What is the predicted reaction? 1º alkyl halide with a strong base? weak base? poor
nucleophile? strong base: Sn2 favored but E2 with strong non-nucleophilic bases
weak base: Sn2 poor nucleophile: no reaction
When are the terms ortho, meta, para used?
when there are 2 substituents on the aromatic ring
In IUPAC naming, what is NH2 on a phenyl ring referred to as?
anilin
