Give the product of the reaction of excess benzene (2 equivalents) with dichloromethane and alcl3.
1 answer:
Hello!
The product of the reaction of excess benzene with dichloromethane is diphenylmethane.
The reaction that benzene undergoes with dichloromethane is a Friedel-Crafts Alkylation, in which firstly Benzene is alkylated to Benzyl Chloride, and after that, the Benzyl Chloride reacts with another equivalent of Benzene to form the compound Diphenylmethane. The Reaction Scheme is shown in the image below:

Answer:
The age of the sample is 4224 years.
Explanation:
Let the age of the sample be t years old.
Initial mass percentage of carbon-14 in an artifact = 100%
Initial mass of carbon-14 in an artifact =
Final mass percentage of carbon-14 in an artifact t years = 60%
Final mass of carbon-14 in an artifact =
Half life of the carbon-14 =
Solving for t:
t = 4223.71 years ≈ 4224 years
The age of the sample is 4224 years.
