Question
A) Identify the strongest acid in the following set and give the correct reasoning.
HClO HBrO HIO
HBrO. Strength of oxyacids with the same number of HO groups increase with increasing electronegativity of the central atom.
HIO. Strength of oxyacids with the same number of HO groups increase with increasing size of the central atom.
HClO. Strength of oxyacids with the same number of HO groups increase with increasing electronegativity of the central atom.
HIO. Strength of oxyacids with the same number of HO groups decrease with increasing size of the central atom.
B) Identify the strongest acid in the following set and give the correct reasoning.
NH3 H2O H2S
NH3. H2O is weaker than NH3 because oxygen is more electronegative and H2S is weaker than H2O because S is larger than O.
H2S. H2O is stronger than NH3 because oxygen is more electronegative and H2S is stronger than H2O because S is larger than O.
H2O. H2O is stonger than NH3 and H2S because oxygen is more electronegative.
H2S. H2O is stronger than NH3 because oxygen is less electronegative and H2S is stronger than H2O because S is smaller than O.
HBrO. Strength of oxyacids with the same number of HO groups increase with increasing electronegativity of the central atom.
HIO. Strength of oxyacids with the same number of HO groups increase with increasing size of the central atom.
HClO. Strength of oxyacids with the same number of HO groups increase with increasing electronegativity of the central atom.
HIO. Strength of oxyacids with the same number of HO groups decrease with increasing size of the central atom.
Explanation / Answer
A
HClO is strong acid
reason is
HClO. Strength of oxyacids with the same number of HO groups increase with increasing electronegativity of the central atom.
B
correct answer is H2S
correct explanation is
H2S. H2O is stronger than NH3 because oxygen is more electronegative and H2S is stronger than H2O because S is larger than O
