The ester ethyl p-nitrobenzoate is more reactive towards nucleophilic acyl substitution than ethyl p-methyoxybenzoate.
similarly, what happens if cellulose is reacted with maleic anhydride C4H2O3? Again, how is the cellulose molecule/structure altered and what are the reaction by-products?
460. mL of hydrochloric acid (HCl) acid is exactly neutralized with 485 mL 0.660 M NaOH solution. What is the concentration of the acid solution.
Dicarbonyl compounds, such as benzil, can be characterized by reaction with o-phenylenediamine to form a substituted quinoxaline.
Consider the reaction 4KO2(s) + 2CO2(g)->2K2CO3(s) + 3O2(g) . How much KO2 is needed to react with 75.0 L of carbon dioxide at STP?
