Q. Melting point of $D_2O$ is higher than $H_2O$ because
Hydrogen
A
$D_2O$ shows stronger H-bonding than $H_2O$
37%
B
chemical reactions of $D_2O$ are slower than $H_2O$
8%
C
$D^+$ reacts slowly than $H^+$
10%
D
bond energy of O-D bond is higher than O-H bond.
45%
Solution:
$D_2O$ shows stronger H-bonding than $H_2O$ and thus shows higher m.p. and b.p.
