Definitions

Question 1

Isolated Diene

Answer 1

The double bonds are separated by more than one single bond C=C-C-C=C

Question 2

Conjugated Diene

Answer 2

The double bonds are separated by one single bond C=C-C=C

Question 3

Cumulated Diene

Answer 3

The double bonds are not separated by any single bonds -C=C=C- (Allene)

Question 4

Lewis Acid

Answer 4

Electron acceptor (electrophile)

Question 5

Lewis Base

Answer 5

Electron donor (nucleophile)

Question 6

Inductive Effect

Answer 6

When a carbocation is more stable because other carbons are sharing electrons thru sigma bonds (covalent)

Question 7

Torsional Strain

Answer 7

When conformations of torsion angles between adjacent bonds are other than 60 degrees. A type of steric strain.

Question 8

Steric Strain

Answer 8

van der Waals forces: when bulky groups repel each other/ get in the way

Question 9

Angle Strain

Answer 9

When a bond angle is tighter than is should be (less than 109.5 in alkanes)

Question 10

Hyperconjugation

Answer 10

pi bond interaction with adjacent bonds
