Why does NH3 forms intermolecular hydrogen bonds whereas PH3 does not ?
[Hint : Due to strong electronegativity, small size of nitrogen atom and presence of lone pair of electrons on N atom.]

Why does NH3 form hydrogen bond but PH3 does not?
Nitrogen is highly electronegative as compared to phosphorus. This causes a greater attraction of electrons towards nitrogen in NH3 than towards phosphorus in PH3. Hence, the extent of hydrogen bonding...

The molar conductivity of the complex CoCl3.4NH3.2H2O is found to be same as that of 3 : 1 electrolyte.
As coordination number of Co is 6 and complex should be A3B or AB3 type, formula is [Co(NH3)4(H2O)2]Cl3. Name : Tetraaminediaqua cobalt (III) chloride Geometrical isomer : 2 (cis and trans)

Ammonia forms the complex ion [Cu(NH3)4]^2+ with copper ions in alkaline solutions but not in acidic solutions. What is the reason for it?
(b) : In acidic solution, NH3 forms a bond with H+ to give NH4+ ion which does not have a lone pair on N atom. Hence it cannot act as...

A solution contains 2.675g of CoCl3·6NH3 (molar mass = 267.5g mol^–1) is passed through a cation exchanger
(b) : No. of moles of CoCl3·6NH3 = (2.675)/(267.5) = 0.01 No. of moles of AgCl = (4.78)/(143.5) = 0.03. Since 0.01moles of the complex CoCl3·6NH3 gives 0.03moles of AgCl on treatment with...
