Answer:
Reaction follows frieldel-craft alkylation mechanism
Explanation:
- Reaction between benzene and chloroform in the presence of
follows friedel-craft alkylation of benzene - Firstly, one equivalent of benzene adds onto chloroform by replacing one equivalent of Cl from chloroform.
- Remaining two equivalent of Cl in chloroform are similarly replaced by two equivalent of benzene to produce triphenylmethane
- Reaction mechanism has been shown below
Answer:
Option b. 22 g of He will have the greatest volume at STP
Explanation:
In order to determine the volume, we apply the Ideal Gases Law equation:
P . V = n . R . T
V = n . R . T / P
R, T and P are the same in all the situation we must define n (number of moles).
The one that has the greatest number of moles will have the greatest volume at STP
22 g of Ne . 1mol / 20.1 g = 1.09 moles of Ne
22g of He . 1mol / 4 g = 5.5 moles of He
22 g of O₂ . 1mol / 32g = 0.68 moles of O₂
22 g of Cl₂ . 1mol / 70.9 g = 0.31 moles of Cl₂
