Draw the mechanism for the dehydration of propan-2-olby concentrated sulphuric acid, using a mechanism that goes through a carbocation intermediate. Show all lone pair electrons, hydrogen atoms and mechanistic arrows. Note: do not draw the structure for H2SO4 as a part of the mechanism

Explanation: Oxygen plays a very vital role in the life of aquatic animals. The dissolved oxygen in the water helps them to breathe under water.

Optimum level of oxygen for deep living animals like oysters, bottom feeders, crabs is around (1-6 mg/L), while the animals living on the upper side like fishes require a higher amount of around (4-6 mg/L).

If the oxygen concentration in the pond is not optimum, there will no aquatic life and hence, the ecosystem will be affected.

Hence, oxygen concentration affects the fishes that live in the pond to a higher extent.
