Alcohol
In IUPAC naming, what is the suffix used for ketone groups? - ANSWERS-one
In IUPAC naming, what is the suffix used for alcohol groups? - ANSWERS-nol
In IUPAC naming, what is the suffix used for esters? - ANSWERS-noate
Benzyl group - ANSWERS
Phenyl group - ANSWERS
ethanoic acid - ANSWERS
(E) isomers vs. (Z) isomers. Which one is observed when the higher ranked molecules are on the
same side? opposite? - ANSWERShighest on same side: Z
highest on opposite sides: E
Electron-withdrawing groups are what type of directors? What is the one and only exception? -
ANSWERSMeta (deactivators)
Halogens
, 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? - ANSWERSlone pairs: activating, ortho, para director
no lone pairs: deactivating, meta director
When are the terms ortho, meta, para used? - ANSWERSwhen there are 2 substituents on the
aromatic ring
In IUPAC naming, what is NH2 on a phenyl ring referred to as? - ANSWERSaniline
Analine - ANSWERS
Amine - ANSWERS
Amide - ANSWERS
If there is a NO2 group present, what IUPAC prefix will also be evident? - ANSWERSnitro
What is the predicted reaction? 1º alkyl halide with a strong base? weak base? poor
nucleophile? - ANSWERSstrong base: Sn2 favored but E2 with strong non-nucleophilic bases
weak base: Sn2
poor nucleophile: no reaction
What is the predicted reaction? 2º alkyl halide with a strong base? weak base? poor
nucleophile? - ANSWERSstrong base: mostly E2
strong non-nucleophilic bases: mostly Sn2
poor nucleophile: Sn1/E2 (slow) in polar, protic solvents
