Flash Cards For Final Exam For Organic Chemistry 1

Front 1

Which will proceed faster, a reaction with -SCH3 or S(CH3)2 ?

Back 1

-SCH3, anions are more nucleophilic than neutral molecules. Therefore reactions with anions proceed faster

Front 2

Which will proceed faster, a reaction with -N(CH3)2 or -O(CH3)2 ?

Back 2

-N(CH3)2, Nitrogen is less electronegative (farther to the left on PT) and therefore more nucleophilic. (same row same charge)

Front 3

Which will proceed faster, a reaction with +Se(CH3)2 or +Te(CH3)2 ?

Back 3

+Te(CH3)2 more polarizable, more Nucleophilic (same column same charge)

Front 4

Which will produce a better leaving group, a reaction which proceed under acidic conditions and there for forms H2O or non acidic conditions?

Back 4

Acidic conditions which forms H2O or other stable neutral product which proceeds faster. not a -OH as in a non acidic reaction.

Front 5

Which will produce a better leaving group and therefore a faster reaction, a reaction which results in I-, F-,OH-?

Back 5

I is a conjugate base of the strong acid HI which makes it the best leaving group, F- is the conjugate strong base of HF, weak acid, and -OH is a strong base

Front 6

A reaction that gives one stereoisomer (out of a few possible)

Back 6

Stereoselective

Front 7

A class of reactions in which stereo isomeric starting material gives stereo isomeric products.

Back 7

Stereospecific

Front 8

Stereo isomeric starting materials which gives the same single stereo isomeric product.

Back 8

each reaction is stereoselective but the class is not sterospecific

Front 9

In SN2 reaction which has a faster rate of reaction: 1st degree, 2nd degree or 3rd degree?

Back 9

1st degree; 3rd degree are nonsense detectors

Front 10

Reactions always proceeds with inversion

Back 10

SN2

Front 11

In SN1 reaction which has a faster rate of reaction: 1st degree, 2nd degree or 3rd degree?

Back 11

3rd degree
