inorganic cumulatively !

Can someone come up with something on the unsymmetrical and symmetrical cleavages of diborane?

Let's start with Qualitative Analysis : -

IMPORTANT POINTS TO BE NOTED:-

(i) Cu Cl 2, Zn Cl2, C6H5NH3 + Cl - (Anilinium chloride) , Ba Cl2 gives chromyl chloride test. But the Chromyl chloride test is not given by chlorides of Ag, Hg, Sb, Sn.

(ii)Ag Cl is not precipitated if AbHO3 is added to [Co (NH3)3 Cl 3]. A Cl is not soluble in H2O, HI and HNO2.

(iii)Ag Cl is not soluble in H2O and dil. HNO3 but soluble in NH4OH, NaCN , KCN, hypo, etc. due to the formation of complexes.

(iv) Ag Br is not soluble in HNO3 but completely soluble in hypo.

(v) Ag Cl, Ag Br , Ag I all are soluble in hypo.

(vi) Ag F is soluble in water.

(vii) Ring test is not reliable in presence of nitrite, bromide, and iodide.

I will keep adding compounds here....

here is first one

Mercuric oxide, HgO : It is obtained as a red solid by heating mercury in air or oxygen

for a long time at 673 K
679K
2Hg + O2 → 2 HgO ( red )

or by heating mercuric nitrate alone or in the presence of Hg
Heat
2Hg ( NO3 )2 → 2HgO + 4NO2 + O2
red

When NaOH is added to a solution of HgCI2, yellow precipitate of HgO are obtained.
Hg2 CI2 + 2NaOH → HgO ↓+ H2O + 2NaCl
(yello)

Red and yellow forms of HgO differ only in their particle size. On heating to 673 K, yellow form changes to red form.
673K
HgO → HgO
Yellow red

It is used in oil paints or as a mild antiseptic in ointments.

If anyone dislike it..plz tell me.[1]

this was posted by tushar, sometimes back :

Bent's rule, which concerns orbital hybridisation of chemical bonds, was stated in 1961 by the American chemist Henry Bent. Originally, it was expressed as follows:
• Atomic s character concentrates in orbitals directed toward electropositive substituents
In other words, more understandable in terms of p-character of hybridised bonds:
• A central atom tends to direct hybrids of higher p character toward more electronegative substituents
