Assign reasons for the following :
(i) In liquid state, hydrogen chloride is a stronger acid than hydrogen fluoride.
(ii) Phosphorus (P4 ) is much more reactive than nitrogen (N2 ).
(d) : Higher is the oxidation state of the central atom, greater is the acidity.
Hence, HClO4 is a stronger acid than HClO3. HNO3 is a stronger acid than HNO2.
Now, greater is...
(i) This is because transition metals have strong metallic bonds as they have a large number of unpaired electrons.
(ii) The catalytic activity of transition metals is attributed to the following...
(i) In aqueous solution Cu+ undergoes disproportionation to form a more stable Cu2+ ion.
2Cu+(aq) → 2Cu2+(aq) + Cu(s)
The higher stability of Cu2+ in aqueous solution may be attributed to its greater negative...
(i) This is due to d-d transition. When visible (white) light falls on a transition metal compounds, they absorb certain radiation of visible light and transmit the remaining ones. The...
(i) Because bond dissociation enthalpy of H—Cl is lower than H—F.
(ii) White phosphorus is more reactive than red phosphorus due to its discrete tetrahedral structure and angular strain. Red phosphorus...
(b) Formic acid is stronger than acetic acid due to its chemical composition. Formic acid is an organic acid as well as active acid in an organic acid.
(a) BF3 due to greater electronegativity of fluorine it withdraws more electrons from central 'B' atom
(b) Sn+4 Greater is the charge on the ion greater is its Lewis acidic strength
