Question 12 :
The valency of Cr in the complex $\left[ \mathrm { Cr } \left( \mathrm { H } _ { 2 } \mathrm { O } \right) _ { 4 } \mathrm { Cl } _ { 2 } \right] ^ { + }$
Question 13 :
Among cellulose, polyvinyl chloride, nylon and natural rubber, in which of the polymer intermolecular force of attraction is weakest?
Question 14 :
Assertion: Transition metals show variable valence.
Reason: Due to a large energy difference between the $ ns^2 $ and $ ( n - 1)d $ electrons.
