Explanation:
The reaction of 1-bromo-2-tert-butylcyclohexane with potassium tert-butoxide is an elimination reaction that occurs by E2 mechanism.
The E2 reaction proceeds faster when the hydrogens are in an antiperiplanar position at an angle of 180 degrees.
This is only attainable in the trans isomer of 1-bromo-2-tert-butylcyclohexane. Hence trans 1-bromo-2-tert-butylcyclohexane reacts faster with potassium tert-butoxide
The composition of the stack gas are :
= 0.8713
= 0.0202
CO = 0.107
<h3 /><h3>What is a mole fraction?</h3>The ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components.
Assuming 100 g of the stack gas. Calculate the mass of each species in this sample according to their percentages.
Mass of : 70% of 100 g = 70 g
Mass of : 15% of 100 g = 15 g
Mass of CO : 15% of 100 g = 15 g
Now calculate the number of moles of each species:
Number of moles of :
= 4.3 mole
Number of moles of :
= 0.10 mole
Mass of CO : = 0.53 mole
Now to calculate the mole fraction of each we use the formula:
Mole fraction of :
= 0.8713
Mole fraction of :
= 0.0202
Mole fraction of CO : = 0.107
Hence, composition of the stack gas are:
= 0.8713
= 0.0202
CO = 0.107
