Consider the mechanism shown here: 2 NO --> N2O2 N2O2 + H2--> N2O2 + H2O (slow step) N2O + H2 ---> N2 + H2O Write the balanced, overall reaction for this mechanism. You do not need to subscript the #atoms in each molecule, use an "equals sign" for the arrow.
As 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?
a) Consider the reaction of HBr with ethylene and propylene. 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.
