<u>Answer:</u> The theoretical yield of triphenylmethanol is 0.173 grams
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
Given mass of benzophenone = 121 mg = 0.121 g (Conversion factor: 1 g = 1000 mg)
Molar mass of benzophenone = 182.21 g/mol
Putting values in equation 1, we get:
The chemical equation for the formation of triphenylmethanol from benzophenone follows:
As, bromobenzene is the limiting reagent. So, it will limit the formation of products
By Stoichiometry of the reaction:
1 mole of bromobenzene produces 1 mole of triphenylmethanol
So, of bromobenzene will produce = moles of triphenylmethanol
Now, calculating the mass of triphenylmethanol from equation 1, we get:
Molar mass of triphenylmethanol = 260.33 g/mol
Moles of triphenylmethanol = moles
Putting values in equation 1, we get:
Hence, the theoretical yield of triphenylmethanol is 0.173 grams
