When heated, allyl aryl ethers and allyl vinyl ethers undergo a reaction called a Claisen rearrangement, a concerted reorganizat
ion of bonding electrons similar to the Diels-Alder reaction. The reaction proceeds through a six-membered, cyclic transition state.Draw the structure of the expected product when this compound undergoes a Claisen rearrangement.For the purposes of this problem, assume that double bonds in an aromatic ring are localized at the positions indicated in the figure
1 answer:
In this case, we assume that the starting compound is phenol which become in phenoxide due to reaction with sodium hydride. Sodium ohenoxide reacts with 3-bromo-1-propene to obtain the allyl aryl ether: allyl phenylether.
The allyl aryl ether undergoes Claisen reanrrangement when is heat between 200 and 250 celsius grades obtaining o-allyl phenol.

Answer:
1) pentane is of higher Molecular mass than propane hence heavier member
2) due to intermolecular hydrogen bonding methanol is liquid having lower molecular weight
3) I) in methanol C = sp3
ii) in methanoic acid C= sp2
5)I) i) The two carbon-oxygen bonds in the methanoate anion, HCO2-, have the same length due to resonance stabilization of the C-O bond
