Heavy Water

Concept: Properties of Heavy Water ( $D_2O$ ) Heavy water contains deuterium (

%5E2H

) instead of hydrogen (

%5E1H

), which makes it heavier and leads to stronger intermolecular interactions.

Step 1: Boiling point

%5Ctext%7BB.P.%20of%20%7D%20D_2O%3EH_2O

Due to stronger hydrogen bonding → Correct

Step 2: Reaction rate

D_2O%20%5Ctext%7B%20reacts%20more%20slowly%7D

Heavier isotope → slower bond breaking (kinetic isotope effect) → Correct

Step 3: Viscosity

%5Ctext%7BViscosity%20of%20%7D%20D_2O%3EH_2O

Stronger intermolecular attraction → Correct

Step 4: Solubility of salts

%5Ctext%7BSolubility%20in%20%7D%20D_2O%3CH_2O

Stronger hydrogen bonding reduces ion solvation → Lower solubility So statement:

%5Ctext%7B%E2%80%9CSolubility%20is%20more%E2%80%9D%7D%20%5Cquad%20%5CRightarrow%20Incorrect

Final Answer: D
