Explanation:
Let us examine the statements in the question carefully. First of all, we will discover that the products of the E2 elimination of the both compounds are isomeric. However Y does not undergo SN2 reaction as X does.
The fact that SN2 reaction does not occur in Y confirms that the bromine atom is attached to a tertiary carbon atom and SN2 reaction does not occur due to steric hinderance. Since X undergoes SN2 reaction in aprotic solvent, the chlorine atom must be attached to a secondary carbon atom.
However, E2 reactions does occur with tertiary alkyl halides when strong bases such as OH^- or RO^- are used.
The question also stated that the catalytic hydrogenation of Z affords 3-ethylpentane.
Putting all these together, the structures of X and Y have been suggested in the image attached to this answer.
Answer : The value of is,
Explanation :
The formula used for is:
............(1)
where,
= Gibbs free energy for the reaction
= standard Gibbs free energy
R = gas constant = 8.314 J/mole.K
T = temperature =
Q = reaction quotient
First we have to calculate the .
Formula used :
Now put all the given values in this formula, we get:
Now we have to calculate the value of 'Q'.
The given balanced chemical reaction is,
The expression for reaction quotient will be :
In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
Now put all the given values in this expression, we get
Now we have to calculate the value of by using relation (1).
Now put all the given values in this formula, we get:
Therefore, the value of is,
