What purpose does fecl3 serve in the electrophilic aromatic substitution reaction between chlorine and benzene?
maria [59]
The reason does FeCl3 serve in the electrophilic sweet-smelling substitution response amongst chlorine and benzene is that it fills in as a Lewis corrosive impetus by responding with the Cl2 and along these lines actuates it toward assault by benzene's π electrons.

Camilla believes that Earth's crust is evenly thick all around the globe, Maclaya thinks that Camilla is wrong, but doesatt know
xenn [34]

Answer:Macaya (floruit 1802), was a Kongolese-born Haitian revolutionary military leader. Macaya was one of the first black rebel leaders in Saint-Domingue to ally himself with the French Republican commissioners Sonthonax and Polverel. He helped to lead forces that recaptured Cap-Français on behalf of the French Republicans.

Macaya was born in west-central Africa, probably in the Kingdom of Kongo, and taken to the French colony of Saint-Domingue as a slave. After the outbreak of the 1791 slave rebellion in northern Saint-Domingue, Macaya became a lieutenant of an elderly rebel commander named Pierrot. Pierrot's rebel forces were based in the hills outside of Le Cap (Cap Francaise), near Bréda plantation by 1793.

In a reaction where an OH group is substituted with a Cl, 15.02 g of 3-phenyl-2-butanol (MW=150.2 g/mol) is the starting materia
Brrunno [24]

Answer:

16.81 g of C₁₀H₁₃Cl

Explanation:

When 3-phenyl-2-butanol reacts with HCl it undergoes a substitution reaction to form 2-chloro-3-phenylbutane and water.

C₁₀H₁₄O + HCl ⇄ C₁₀H₁₃Cl + H₂O

The molar mass of 3-phenyl-2-butanol is 150.2 g/mol and the molar mass of 2-chloro-3-phenylbutane is 168.1 g/mol. The molar ratio is 1:1. Then, for 15.02 g of 3-phenyl-2-butanol, the theoretical yield is:

15.02gC_{10}H_{14}O.\frac{168.1gC_{10}H_{13}Cl}{150.2gC_{10}H_{14}O} =16.81gC_{10}H_{13}Cl
