Chemistry · EQUILIBRIUM
हिन्दीGiven below are two statements: Statement I: Across a period from left to right in the periodic table, the polarity of the H-A bond is the deciding factor in determining the acid strength. Statement II: Down a group in the periodic table, the electronegativity difference is the deciding factor in determining the acid strength. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 3
Statement I is correct but Statement II is incorrect.
Explanation
Across a period, bond polarity determines acidity. Down a group, H-A bond strength (not electronegativity) is the deciding factor. Thus, Statement I is correct and Statement II is incorrect.
