2. Assertion : In crystal lattice the size of the cation is larger in a tetrahedral hole than in an octahdral hole. Reason : The cations occupy more space than anions in crystal packing.

a. If both assertion and reason are true and the reason is the correct explanation of the assertion

b. If both assertion and reason are true but reason is not the correct explanation of the assertion

c. If assertion is true but reason is false

d. If the assertion and reason both are false

e. if assertion is false but reason is true.

Ans. d

Explaantion : Tetrahedral holes are smaller in size than octahedral holes. Cations usually occupy less space than anions
