Question

Diamond is made up of carbon and why it is stronger than other carbons that we see in our daily life?

Answer 1

An extremely rare allotrope of carbon, lonsdaleite, has been calculated, in pure form, to be 58% stronger than diamond. Lonsdaleite is a diamond-like carbon network which has graphite's hexagonal structure. It is made when meteorites containing graphite hit another body, such as Earth.

Answer 2

find is stronger than other carbons because the bonding between the layers of other carbon is weak thus the layers get detached easily while in diamond the bonding between the layers is stronger as compare to other
