Answer: Rotation occurs at single bonds that are sigma bonds. Rotational barrier is the amount of activation energy required to covert rotamer to another by rotation that occurs around the sigma bond(C-C single bond). Due to the presence of steric hindrance that is the nonbonding interaction effects the reactivity of ions and molecules, activation energy increases. So the rotational barrier in butenyl cation is high.
Answer:
70
Explanation:
20 x 5 vials = 100mg
therefore 5 vials required each day.
Two weeks = 14 days
14 days x 5 vials = 70 vials
