Assertion `H_(2)O` has maximum density at `4^(@)C` Hence in water ice will sink to the bottom at `4^(@)C`
Reasoning Up to `4^(@)C` more and more hydrogen bonds are formed between `H_(2)O` molecules .

Options

A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`
B. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`
C. If `(A)` is correct but `(R )` is incorrect
D. If `(A)` is incorrect but `(R )` is correct

Answer

D

Explanation

Due to H-bonding ice forms cage like structure Thus ice occupies more volume add `4^(@)C` molecules come closer Hence density of water is highest at `4^(@)C` Therefore ice floats over water .
