19. Diamond and graphite show different physical properties although they are made uo of carbon. Name
this relationship between diamond and graphite. Give the basis of this relationship also..
Answers
Answer:
The differences in their properties are due to the way the carbon atoms are arranged in their structures, with the tetrahedral structure of diamond forming a hard substance, while the hexagonal structure of graphite forms a softer substance.
Diamond: Giant covalent structure, with each carbon covalently bonded to four other carbon atoms in a tetrahedral arrangement to form a rigid structure.
Graphite: It is also Giant covalent structure, with each carbon covalently bonded to three other carbon atoms in a hexagonal arrangement.
HOPE THIS HELPS YOU!☺️
Answer:
diamond and graphite are two allotropes of carbon.
in diamond one carbon atom forms bonds with 4 other carbon atoms and form a three dimensional structure.
in graphite one carbon atom forms bonds with 3 other carbon atoms to form layers.
diamond is hardest substance known and graphite is smooth and slippery.
although their physical properties are different they are chemically same as they are formed by covalent bonds.
