Question
Refractive index of a solid is observed to have the same value along all directions. Comment on the nature of this solid. Would it show cleavage property?
✓
Answer
As the solid has same value of refractive index along all directions, it is isotropic in nature and hence amorphous. Being amorphous solid, it will not show a clean cleavage and when cut, it will break into pieces with irregular surfaces.

The carbon-oxygen bond in phenol is slightly stronger than that in methanol. Why?
Compound $‘A’$ with molecular formula $C_4H_9Br$ is treated with aq. $KOH$ solution. The rate of this reaction depends upon the concentration of the compound ‘A’ only. When another optically active isomer $‘B’$ of this compound was treated with aq. $KOH$ solution, the rate of reaction was found to be dependent on concentration of compound and $KOH$ both.
