Question

Statement: Diamond is the hardest compound.

State whether the given statement is true or false.

• A. True
• B. False

Answer 1

The correct option is B False

Diamond is no more the hardest known material. Wurtzite boron nitride and lonsdaleite exist naturally or have been made in the lab. So, until now, no one had realised their superior strength. The simulation showed that wurtzite boron nitride would withstand $18$ per cent more stress than diamond, and lonsdaleite $58$ per cent more. If the results are confirmed with physical experiments, both materials would be far harder than any substance ever measured.

Hence, the correct option is $\text{false}$
