NEETChemistryp Block Elements (Group 15, 16, 17 & 18)
Diamond is a covalent substance, yet it has a high melting point. Why?
Options
- ADiamond forms ionic bonds that contribute to its high melting point.
- BDiamond has a three-dimensional network involving strong C—C bonds, which are very difficult to break.
- CDiamond has weak Van der Waals forces that contribute to its high melting point.
- DDiamond undergoes sublimation rather than melting.
Correct answer
B. Diamond has a three-dimensional network involving strong C—C bonds, which are very difficult to break.
Step-by-step solution
Correct Option is : (B) Diamond has a three-dimensional network involving strong C—C bonds, which are very difficult to break.
