Topics of UHS/MCAT syllabus not covered in Fsc Books This post will contain the topics with explanation which are a part of MCAT syllabus but are not covered in FSc books. Inertness Of Nitrogen: Molecular nitrogen is inert under ordinary conditions existing as diatomic nitrogen N 2 . The presence of a very strong triple covalent bond renders it nonreactive under normal circumstances. Nevertheless nitrogen does react with alkali metal lithium to form a compound Li 3 N, even under ordinary conditions. Under high temperature and pressure and with right catalyst nitrogen becomes more reactive. Haber's process uses such conditions to form ammonia. Inert atmosphere consisting of gases such as argon , nitrogen or helium are commonly used in chemical reaction chambers and in storage containers for water and air sensitive substances to prevent any side reaction.
