Melting point of D2O is higher than H2O because

Question

Melting point of D2O is higher than H2O because (A) D2O shows stronger H-bonding than H2O (B) chemical reactions of D2O are slower than H2O (C) D+ reacts slowly than H+ (D) bond energy of O-D bond is higher than O-H bond.

D2O shows stronger H-bonding than H2O and thus shows higher m.p. and b.p.

Q. Melting point of $D_{2} O$ is higher than $H_{2} O$ because

$D_{2} O$ shows stronger H-bonding than $H_{2} O$

chemical reactions of $D_{2} O$ are slower than $H_{2} O$

$D^{+}$ reacts slowly than $H^{+}$

bond energy of O-D bond is higher than O-H bond.

$D_{2} O$ shows stronger H-bonding than $H_{2} O$ and thus shows higher m.p. and b.p.

Q. Melting point of D2​O is higher than H2​O because

D2​O shows stronger H-bonding than H2​O

chemical reactions of D2​O are slower than H2​O

D+ reacts slowly than H+
