Question 20

Alkyl group

Answer 20

An alkane missing one hydrgen

Question 21

Isopropyl

Answer 21

Question 22

Sec-

Answer 22

The prefix “sec” or “s” is used when the functional group is bonded to a secondary carbon. This prefix is only useful for a four-carbon chain. It is not applicable with a shorter chain, and it is often ambiguous when the chain has five or more carbons.

Question 23

Tert-butyl

Answer 23

The prefix “tert” or “t” is used when the functional group is bonded to a tertiary carbon.

Question 24

Branched alkane said are ______in energy then straight chain alkane.

Answer 24

Lower in energy(more stable)

Question 25

Conformations

Answer 25

A variety of possible three dimensional shape a compound can adopt

Question 26

Dihedral angle or Torsional angle

Answer 26

The angle between two planes,where each plane is defined by three atoms, 60 degrees

Question 27

Staggered conformation

Answer 27

Two atoms and/or group whose dihedral angle is 60 degrees. Their bonds to the axis of rotation are not aligned. Lowest energy conformation

Question 28

Eclipsed conformation

Answer 28

Two atoms and/or groups whose dihedral angle is 0 degrees. Their bonds on the axis of rotation are aligned,highest in energy

Question 29

Degenerate

Answer 29

Systems that are equal in energy

Question 30

Torsional strain

Answer 30

Strain caused by van der Waals repulsion which can be reduced or eliminated by rotation around a single bond.strain between the eclipsed atoms

Question 31

Anti conformation

Answer 31

The conformation with a dihedral angle of 180 degrees

Question 32

Angle strain

Answer 32

The increase in energy associated with a bond angle that has deviated from the preferred angle of 109.5 degrees
