Answer:
See explanation and image attached
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:
1.
Explanation:
Hello,
In this case, for the given reaction we first assign the oxidation state for each species:
Whereas the half reactions are:
Next, we exchange the transferred electrons:
Afterwards, we add them to obtain:
By adding and subtracting common terms we obtain:
Finally, by removing the oxidation states we have:
Therefore, the smallest whole-number coefficient for Sn is 1.
