Question

What is an allotrophic compound?

Answer 1

Allotropy or allotropism (from Greek ἄλλος (allos), meaning "other", and τρόπος(tropos), meaning "manner, form") is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of these elements. Allotropes are different structural modifications of an element;[1] theatoms of the element are bonded together in a different manner. For example, theallotropes of carbon include diamond (where the carbon atoms are bonded together in a tetrahedral lattice arrangement), graphite (where the carbon atoms are bonded together in sheets of a hexagonal lattice), graphene (single sheets of graphite), andfullerenes (where the carbon atoms are bonded together in spherical, tubular, or ellipsoidal formations). The term allotropy is used for elements only, not forcompounds.
