Short Answer TypeThe chemistry of corrosion of iron is essentially an electrochemical phenomenon. Explain the reactions occurring during the corrosion of iron in the atmosphere.
State reasons for each of the following:
The N-O bond in is shorter than the N-O bond in
State reasons for each of the following:
SF6 is kinetically an inert substance.
The kinetic inertness of SF6 can be explained on the basis of its structure.
The six fluoride (F-) atoms protect the sulphur atom from attack by the regents to such an extent that even thermodynamically most favorable reactions like hydrolysis do not occur.
State reasons for each of the following:
(i) All the P-Cl bonds in PCl5 molecule are not equivalent.
(ii) Sulphur has a greater tendency for catenation than oxygen.
