Triphenylmethanol can also be prepared by reacting ethyl benzoate with phenylmagnesium bromide, and by reacting diethylcarbonate
with phenylmagnesium bromide. Write stepwise rxn mechanisms for these two reactions
1 answer:
Answer:
Both reactions proceeds through nucleophilic acyl substitution reaction
Explanation:
- Both these two reactions proceeds through nucleophilic acyl substitution reaction where phenyl magnesium bromide replaces one ethoxide ion.
- Then another another equivalent of phenyl magnesium bromide give nucleophilic addition reaction with resulting keto group to produce triphenylmethanol
- Full reaction mechanism has been shown below

Answer:
168.0 g
Explanation:
First thing, write a balanced chemical equation:
n(H2SO4) = concentration * volume
= 1.0 M * 2.0 L
= 2.0 mol
According to the balanced equation, 1 mol of acid requires 2 mol of sodium bicarbonate. This means that 2 mol of acid requires 2 mol of sodium bicarbonate. What mass of sodium bicarbonate is this?
mass (NaHCO3) = number of moles * molar mass
= 2.0 mol * 84.0065 g/mol
= 168.0 g
