Question

iv) comment on the boiling and freezing points of sea water compared to pure water at 1 atm pressure.

Answer 1

KI in acetone undergoes SN2 reaction with each of P, Q, R and S. The rates of the reaction vary as (a) P > Q > R > S (b) S > P > R > Q (c) ...

Answer 2

Answer:

Sample 'B' will not freeze at 0°C because it is not pure water. At one atmospheric pressure, the boiling point of pure water is 100°C and the freezing point of pure water is 0°C.
