In diamond, each carbon atom is bonded to four other carbon atoms to form

(a) a hexagonal array
(b) a rigid three-dimensional structure
(c) a structure in the shape of a football
(d) a structure of a ring

Dear Student,

In diamond, each carbon atom is covalently bonded to four other carbon atoms.
This arrangement of carbon atoms gives rise to a tetrahedral structure.
These small tetrahedrons combine to form a rigid three-dimensional network in which each carbon atom is bonded to four other carbon atoms throughout the crystal lattice.

Structure of diamond


Hence, the correct option is (b).
