2
Q

3
Q
What is required to rotate a bond
A
Energy and the amount depends on the bond.
4

5
Q
Staggered isomer?
A

6
Q

A
The C and H are aligned with each other
7
Q
Angle between staggered H’s
A
60
8
Q
Angle between H in eclipsed
A
0
9
Q
In a wave diagram does the staggered sit in the bumps or dips
A
Dips as it has lower energy and more favourable
