At roomtemperature the reaction of propylene with HBr is much faster than thereaction with ethylene.Using reaction energy diagrams and your knowledge of carbocationstability explain why this is so. b) Xylene (dimethylbenzene) is a commonly used chemical in the printingindustry and as a cleaning solvent for oily waste. It is also used whenpreparing histological samples to remove waxes from biological samples.Draw the three possible structures for this compound and give the UPACnames for each. Define which structures are ortho, meta, and para.46. The Strength of Nucleophile: Which one is the strongest nucleophile? OH (B) 0-CH, -CH, (D) O (C) O (A) O (D) O (B)

- The following compounds are major products of an elimination reaction with an alkyl halide. Determine the structure of the alkyl halide and write the overall reaction mechanism.Identify which substitution mechanism best fits the following statement: The reaction proceeds through a concerted mechanism. A) SN1 B) SN2As we will learn, many antioxidants–compounds that prevent unwanted radical oxidation reactions from occurring–are phenols, compounds that contain an OH group bonded directly to a benzene ring.a.) Explain why homolysis of the O–H bond in phenol requiresconsiderably less energy than homolysis of the O–H bond in ethanol(362 kJ/mol vs. 438 kJ/mol).b.) Why is the C–O bond in phenol shorter than the C–O bond in ethanol?
