Question

Which phrase describes the molecular structure and properties of two solid forms of carbon, diamond and graphite?(1) the same molecular structures and the same properties
(2) the same molecular structures and different properties
(3) different molecular structures and the same properties
(4) different molecular structures and different properties

Answer 1

I think the answer is (4) different molecular structures and different properties. Both structure are crystal. The structure of graphite is organized in layers. And structure of diamond is a strong network of atoms. Also due to the different structures, they have different properties.
