Question:
Consider the following statements:
Statement-I: The order of electronegativity of B, Al, In, Tl is \(B>Tl>Al>In\)
Statement-II: Boric acid is a weak protic acid
Consider the following statements:
Statement-I: The order of electronegativity of B, Al, In, Tl is \(B>Tl>Al>In\)
Statement-II: Boric acid is a weak protic acid
Statement-I: The order of electronegativity of B, Al, In, Tl is \(B>Tl>Al>In\)
Statement-II: Boric acid is a weak protic acid
Show Hint
Verify element properties and acid nature carefully.

- Both statement-I and statement-II are correct
- Both statement-I and statement-II are not correct
- Statement-I is correct, but statement-II is not correct
- Statement-I is not correct, but statement-II is correct
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Electronegativity order
Correct order is \(B>Al>In>Tl\), so statement-I is incorrect.
Step 2: Nature of boric acid
Boric acid is a weak monobasic acid, but it acts as a Lewis acid, not protic acid. Hence statement-II is incorrect.
Step 3: Conclusion
Both statements are incorrect.
Correct order is \(B>Al>In>Tl\), so statement-I is incorrect.
Step 2: Nature of boric acid
Boric acid is a weak monobasic acid, but it acts as a Lewis acid, not protic acid. Hence statement-II is incorrect.
Step 3: Conclusion
Both statements are incorrect.
