Answer:
(a) (A) (b)
(c) (d)
(e) [1]
Reactions
Orange in colour
(Calcium
nitride)
[1]
(b)(i)
(ii)
Or
(a) (i) Solid ionises
as
Tetrahedral Octahedral [1]
(ii) is
thermodynamic unstable since its decomposition into is an
exothermic change.
Since, randomness increases due to increase in number of
molecules hence entropy also increases. We know
Thus,
Thus, conversion of into is spontaneous
taking place with decrease in free energy. Hence, is
thermodynamic unstable. [1]
(iii) Most of the reactions of F^ are exothermic due to the
small and strong bond formation with other elements. [1]
(b) (i) Structure of
Square pyramidal,
(ii) Structure of
Each P-atom is sp3 hybridised.
