Here's what I get
Explanation:
The reaction is an E1 elimination of an alcohol to form an alkene. It has three steps:
1. Protonation
The alcohol is protonated with aqueous sulfuric acid to convert it into a better leaving group.
2. Loss of the leaving group
A water molecule leaves in a unimolecular process to form a stable 3° carbocation.
3. Loss of an α-hydrogen
A water molecule removes an α-hydrogen, forming 2-methylpropene and regenerating the original hydronium ion.
Answer : The molar volume of the solution is,
Explanation : Given,
Partial molar volumes of component A =
Partial molar volumes of component B =
Mole fraction of component A = 0.4
First we have to calculate the mole fraction of component B.
As we know that,
Now we have to calculate the molar volume of the solution.
Expression used :
where,
= partial molar volumes of component A
= partial molar volumes of component B
= molar volume of the solution
= mole fraction of of component A
= mole fraction of of component B
Now put all the give values in the above expression, we get:
Therefore, the molar volume of the solution is,
