Consider the following statements related to diamond and graphite.
I. Both diamond and graphite are used as abrasives.
II. Diamond and graphite have different arrangements of carbon atoms.
III. The carbon atoms in graphite have a different number of neutrons from those in diamond.
IV. The carbon atoms in both graphite and diamond have four single covalent bonds. The incorrect statement(s) is/are
A. I and III
B. II and IV
C. I, III and IV
D. All of these
Graphite is commonly used as an abrasive, but diamond is not used.
The number of neutrons in carbon atoms present in both graphite and diamond are the same. It only depends upon the nature of the element, and both are allotropes of the same element carbon.
In diamond, each carbon is covalently bonded to 4 other carbon atoms whereas in graphite, each carbon is covalently to 3 other carbon atoms.
