or simply 2,8 it is isoelectronic with argon
Acceleration is the rate of change and is constantly positive
The answers for Acceleration:
m/s^2
Change in velocity over change in time
Velocity is the speed of the object but also involves direction can be both negative and positive
The answers for Velocity:
m/s
Can be positive or negative
Change in displacement over change in time
Both Acceleration and Velocity:
A rate of change
Answer:
When cinnamic acid react with bromine ,addition reaction rapidly occur on alkene functional group to form dibromo product
Explanation:
Phenyl ring is an aromatic hydrocarbon ,when aromatic hydrocarbons react with Cl2,Br2 or KMnO4 no reaction occur ,where as unsaturated hydrocarbon like alkene react .Aromatic hydrocarbon with these reagents undenr different conditions undergoes subtituition reaction.They react with bromine in presence of lewis acid catalyst ferric bromide.
