The correct statement regarding P is/are
(I) electrical conductivity decreases with increase in temperature
(II) M-graphite compounds are coloured.
(III) Mechanism of conductivity in M-graphite complexes are similar to conductivity in n-type semiconductors.
(IV) In product planarity and delocalization of layers are retained.
Detailed Solution for Main Group Elements - Question 13

Metal graphite complexes has conductivity like Metals and their conductivity decreases with increase in temperature.
These complexes have excess electron in valence band. Hence, their conductivity is due to migration of free electron.
