Benzyl Amine is synthesized from Toluene in two steps;
Step 1: Bromination of Methyl Group in Toluene: Bromination is carried out on methyl group present on Benzene ring through free radical mechanism by treating toluene with <span>N-Bromosuccinimide (NBS) and Benzyl Bromide is formed.
Step 2: Benzyl Bromide into Benzyl Amine; This step is carried out utilizing a neme reaction "Gabriel Reaction". Benzyl bromide is treated with </span>Potassium Phthalamide and an intermediate is formed which on treatment with Hydrazine produces Benzyl amine.
Answer : The energy removed must be, 29.4 kJ
Explanation :
The process involved in this problem are :
The expression used will be:
where,
= heat released for the reaction = ?
m = mass of benzene = 94.4 g
= specific heat of solid benzene =
= specific heat of liquid benzene =
= enthalpy change for fusion =
Now put all the given values in the above expression, we get:
Negative sign indicates that the heat is removed from the system.
Therefore, the energy removed must be, 29.4 kJ
Answer:
It is always twice the value of the actual yield.
