Nitrogenous base:
These are heterocyclic organic compound that comprise two or more nitrogen atoms in ring skeleton. These are called bases as the lone pairs of electrons on the nitrogen atoms make them like a Lewis bases.
wht is the difference between molar mass & molecular mass?
According to Bohr's principle, the relation between principle quantum number and radius of orbit is: (1) r ∞ n (2) r ∞ n 2 (3) ∞1/n (4) r∞ 1/ n 2 Ans: r
