Question 4 Consider heptane, a linear compound composed of 7 carbons and 16

hydrogens. In this experiment, would you expect this compound to have

a small or large retention factor in this experiment?

The retention factor would be high

Explanation:

The retention factor can be affected by the temperature, or affected by the composition of the solvent, when the FM are liquid.

Heptene is a derivative of the distillation of oil, it is a chemical compound that is made up of seven carbons, that is why it begins with the prefix hept.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
