Assertion (A): The bond angle C-O-C in ethers is slightly greater than tetrahedral angle. Reason (R): This is because of the repulsive interaction between the two bulky alkyl groups.
Assertion (A): Molecularity of reaction is determined experimentally. Reason (R): Molecularity is applicable only for an elementary reaction and not for a complex reaction.
On mixing 30 mL of acetone with 20 mL of chloroform, the total volume of solution is:
The freezing point of one molal KCl solution, assuming KCl to be completely dissociated in water, is : (Kf for water = 1.86 K kg mol -1)
