Question 3

Conjugated double bond

Answer 3

Double bonds that alternate with single bonds, with interaction by overlap of the p orbitals in the pi bond

Question 4

Isolated Double Bond

Answer 4

Double bonds separated by two or more ingle bonds

Question 5

Cumulated double bond

Answer 5

successive double bonds with no intervening single bonds.

Question 7

Heats of hydrogenation

Answer 7

The enthalpy of reaction that accompanies the addition of hydrogen to a mole of an unsaturated compound.

Question 8

Lower heat of hydrogenation means

Answer 8

a more stable molecule

Question 9

Resonance energy

Answer 9

the extra stabilization provided by delocalization, compared with a localized structure.

Question 10

Bonding molecular orbitals

Answer 10

orbitals that are lower in energy than the isolated atomic orbitals.

Question 11

Antibonding molecular orbitals

Answer 11

orbitals that are higher in energy than the isolated atomic orbitals

Question 12

nonbonding molecular orbitals

Answer 12

orbitals that have the same energy as the isolated atomic orbitals.

Question 13

orbitals are a mathematical representation of probability of electron density.

Answer 13

ye

Question 14

constructive overlap

Answer 14

an overlap of orbitals that contributes to bonding

Question 15

destructive overlap

Answer 15

An overlap of orbitals that contributes to antibonding

Question 16

Diels-Alder reactants

Answer 16

Diene (electron rich) reacts with an (electron poor) alkene to form a cyclohexene ring.

Question 17

Diels-Alder reactant requirements (diene)

Answer 17

S-trans must be switched to s-cis before reacting (Constructive overlap needs to occur, trans too far)

Question 18

Dienes locked in the s-trans

Answer 18

will not undergo diels alder

Question 19

Dienes locked in s-cis

Answer 19

will readily undergo diels alder

Question 20

Endo rule

Answer 20

The stereo chemical preference for electron-poor substituents on the dienophile to assume endo position in a bicyclic Diels-Alder product.

Question 21

D or EDG is

Answer 21

an electron donor group

Question 22

W or EWG

Answer 22

Electron withdrawing group

Question 23

Conservation of Orbital Symmetry

Answer 23

A theory of pericyclic reactions stating that the Molecular orbitals of reactants must flow smoothly into the Molecular orbitals of the product.

Question 24

Homo

Answer 24

highest occupied molecular orbital

Question 25

Lumo

Answer 25

lowest unoccupied molecular orbital

Question 26

Lumo pushes into homo or the reverse

Answer 26

reverse,

Homo pushes into Lumo.
