Question:
Statement I: Boron does not exhibit allotropy
Statement II: Boron is extremely hard and black coloured solid
Statement I: Boron does not exhibit allotropy
Statement II: Boron is extremely hard and black coloured solid
Statement II: Boron is extremely hard and black coloured solid
Show Hint
Allotropy is common in elements like carbon, sulfur, and boron — be cautious with such general statements.

- Both I \& II are correct
- Both I \& II are not correct
- I is correct but II is not correct
- I is not correct but II is correct
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Statement I is incorrect: Boron does exhibit allotropy (e.g., crystalline and amorphous forms).
Statement II is correct: Crystalline boron is extremely hard and appears black in color.
Statement II is correct: Crystalline boron is extremely hard and appears black in color.
