Hexachlorane Production and Derivative

Hexachlorane is produced by irradiating benzene and chlorine with mercury-quartz lamps in the industry. It is a chlorinated hydrocarbon compound.

Calculation of Hexachlorane Yield

To calculate the amount of hexachlorane that can be obtained from the reaction between 260g of benzene and 300g of chlorine, we need to determine the limiting reactant. The limiting reactant is the reactant that is completely consumed in the reaction and determines the maximum amount of product that can be formed.

To find the limiting reactant, we compare the number of moles of benzene and chlorine. The balanced chemical equation for the reaction is:

C6H6 + 6Cl2 -> C6Cl6 + 6HCl

The molar mass of benzene (C6H6) is 78.11 g/mol, and the molar mass of chlorine (Cl2) is 70.90 g/mol.

The number of moles of benzene can be calculated using its molar mass and mass:

Number of moles of benzene = mass of benzene / molar mass of benzene Number of moles of benzene = 260g / 78.11 g/mol

The number of moles of chlorine can be calculated in the same way:

Number of moles of chlorine = mass of chlorine / molar mass of chlorine Number of moles of chlorine = 300g / 70.90 g/mol

Now, we compare the moles of benzene and chlorine to determine the limiting reactant. The reactant with the smaller number of moles is the limiting reactant.

Let's calculate the moles of benzene and chlorine:

Number of moles of benzene = 260g / 78.11 g/mol = 3.33 mol Number of moles of chlorine = 300g / 70.90 g/mol = 4.23 mol

Since benzene has fewer moles than chlorine, benzene is the limiting reactant.

To calculate the amount of hexachlorane produced, we need to use the stoichiometry of the reaction. From the balanced equation, we can see that 1 mole of benzene produces 1 mole of hexachlorane.

Therefore, the amount of hexachlorane produced is equal to the number of moles of benzene:

Amount of hexachlorane = number of moles of benzene = 3.33 mol

To convert the moles of hexachlorane to grams, we use its molar mass. The molar mass of hexachlorane (C6Cl6) is 290.8 g/mol.

Mass of hexachlorane = amount of hexachlorane * molar mass of hexachlorane Mass of hexachlorane = 3.33 mol * 290.8 g/mol

Calculating the mass of hexachlorane:

Mass of hexachlorane = 3.33 mol * 290.8 g/mol = 967.4 g

Therefore, approximately 967.4 grams of hexachlorane can be obtained from the reaction between 260g of benzene and 300g of chlorine.

Derivative of Hexachlorane

Hexachlorane is a derivative of the hydrocarbon benzene. It is formed by replacing six hydrogen atoms in benzene with chlorine atoms.
