H_(2)S is. more acidic than H_(2)O because

Knowledge Check

  • H_(2)O has higher boiling point than H_(2)S because

    A
    `H_(2)S` is a smaller molecule and hence more closely packed
    B
    the bond angle of `H_(2)O` is more than `H_(2)S` and hence `H_(2)O` molecule are more tightly packet
    C
    the intermolecular hydrogen bonding in liquid `H_(2)O`
    D
    the latent head of voparisation is higher for `H_(2)O` than for `H_(2)S`
  • H_(2)O has a higher boiling point than that of H_(2)O due to

    A
    `H_(2)S` molecular weight is more than `H_(2)O`
    B
    Dispersion forces between water molecules are higher than `H_(2)S`
    C
    Strong ionic bonds between water molecules
    D
    Hydrogen bonds between water molecules
  • Statement-I: D_(2) molecules is more stable than H_(2) . Statement-II: The bond dissociation energy of D_(2) is more than of H_(2) .

    A
    If both Statement-1 `&` Statement-II are True `&` the Statement-II is not a correct explanation of the Statement I.
    B
    If both Statement-I `&` Statement-II are True but Statement-II is not a correct explanantion of the Statement-I.
    C
    If Statement-I is True but the Statement-II is False.
    D
    If Statement-I is False but the Statement-II is True.

    Assertion :D_(2)O has higher boiling point than H_(2)O . Reason : Viscosity of H_(2)O(l) is less than that of D_(2)O(l) .

    Statement-1:Boiling point temperature of H_(2)O_(2) is little more than of H_(2)O . Statement-2: Dipole moment of H_(2)O_(2) is little more than of H_(2)O

    The boiling point of D_(2)O is greater than H_(2)O_(2) It is because

    Statement-1. H_(2)O_(2) decomposes NaHCO_(3) to evolve CO_(2) gas Statement-2. H_(2)O_(2) is a weaker acid than H_(2)CO_(3) acid.

    H_2S is more acidic than H_2O . The reason is
