I am reading Ignition! by Clark and Asimov and I am searching for books which would clear up all/some of the following questions:

• Why are nitrogen compounds so reactive?
• Why is furfuryl alcohol, aniline and especially hydrazine so suitable for hypergolic rocket fuel?
• Why does adding sulfuric acid to nitric acid sometimes help combustion?
• What is an endemic mixture?
• What are the exact reactions between RFNA and the hypergolic fuels?

Context: I am a physicist and had organic/anorganic chemistry but I am not so fluent in these fields as to understand the reasoning behind choosing nitrogen based fuels and all of the stuff above.
