Halides and halide complexes
Almost all elements create thermodynamically stable halides. The general stability sequence is F>Cl>Br>I, that in covalent compounds follows the supposed order of bond strengths, and in ionic compounds which of lattice energies. The thermodynamic stability of fluorides (and the kinetic reactivity of F2) is also aided through the weak F-F bond. Several halides can be made through direct combination, but fluorinating agents like ClF3 are sometimes employed in preference to F2, that is very difficult to handle.
The bonding and structural trends in halides follow identical patterns to those in oxides. Several nonmetallic elements create general molecular compounds where halogen atoms each have a single bond to another element. This is right also for metals in high oxidation states (example UF6 and TiCl4). The compounds might be solids, gases or liquids, with volatility in the order F>Cl>Br> I as expected from the strength of van der Waals' forces. HF is exceptional due to strong hydrogen bonding, in the hydrogen halides. HF is a weak acid in water, another HX compounds being strong acids.
The given amines are CH3NH2, (CH3)2NH,NH3,NH2Br. The amines list is from strongest base to weakest . (CH3)2NH CH3NH2.

The energy required to dislodge electron from excited isolated H-atom, IE 1 = 13.6 eV is: (1) = 13.6eV (2) > 13.6eV (3) 3.4 eV
I well know about electromagnetic spectrum but I did not know the any scope of spectroscopy & I want to know about I r spectra in detail & absorption spectroscopy.
