19
Q

same molecular formula, different connectivity

A

structural/constitutional isomer

20
Q

differ in rotation around sigma bonds (no bond breaking required to interconvert)

A

conformational isomers

21
Q

Configurational isomers

A

require bond breaking to interconvert

22
Q

highest energy state/least stable conformation

A

totally eclipsed

23
Q

stability of conformations (highest stability –> lowest stability)

A

antistaggered > gauche > eclipsed

24
Q

For substitutued rings, the bulkiest group will favor the…

A

it wil favor the equatorial position to reduce nonbonded strain (flagpole interactions) with axial groups int eh molecule

25
Q

Specific rotation

A

[α] = αobs/c x l

[α] is specific rotation in ˚

αobs = observed rotation in degrees

“c” = concentration in g/mL

‘l” = path length in dm

26
Q

meso compound

A

a molecule with chiral centers that has an intenral plane of symmetry

27
Q

Which functional groups are considered terminal functional groups?

A

aldehydes and COOH

28
Q

The common names for the aldehydes and COOH that contain only one carbon start with what prefix?

A

Form– is a prefix shared by the common names of methanoic acid (formic acid) and methanal (formaldehyde)
