Select the incorrect statement based on the following half-reaction -
In which of the following complexes, change in colour is not observed on heating ?
Due to d10 configuration Zn2+ does not impart any colour on heating
Find the total number of Aldol products in given reaction.
The reaction : 2NO2(g) ⇌ N2O4(g), has ΔG0298K = -6kJ mol-1. If in the reaction mixture the partial pressure of NO2 is 0.4 atm and partial pressure of N2O4 is 0.2 atm than -
Select a incorrect match :
Na+ + EDTA4– → Na4 EDTA
Which statement is not true :
The standard heat of combustion of carbon(s), sulphur(s) and carbon disulphide(l) are – 390, – 290 and – 1100 kJ/mol respectively. The standard heat of formation of carbon disulphide (l) is -
C(s) + 2S(s) → CS2(l)
ΔfH° = -390 - (290) × 2 - (-1100)
= + 130 kJ mol-1
of Mn, Fe and Co is +1.57, + 0.77 and + 1.97 respectively then this irregularity is due to
Mn → [Ar] 3d5 4s2 ; Mn3+ → d4
Fe → [Ar] 3d6 4s2 ; Fe2+ → d6, Fe3+ → d5
Co → [Ar] 3d7 4s2 ; Co3+ → d6
