Numerical Stoichiometry In Substitution
If 0.20 mol of 1-bromopropane reacts completely with aqueous NaOH, the maximum amount of propan-1-ol formed will be:
Select the correct option:
Solution
0.20 mol
Hydrolysis of 1-bromopropane with aqueous NaOH follows a 1:1 stoichiometry: R-Br + OH- -> R-OH + Br-. Hence 0.20 mol of haloalkane can produce at most 0.20 mol of alcohol if reaction is complete. Unit check confirms answer is in moles (mol).

Solution
Correct Answer:
0.20 mol
Hydrolysis of 1-bromopropane with aqueous NaOH follows a 1:1 stoichiometry: R-Br + OH- -> R-OH + Br-. Hence 0.20 mol of haloalkane can produce at most 0.20 mol of alcohol if reaction is complete. Unit check confirms answer is in moles (mol).
