Identify the correct statement

Options

A. Non-directional covalent bonds are present throughout the crystal lattice of diamond
B. Fullereness are the pure forms of carbon
C. C-C bond length in the layer of graphite is 154 pm
D. Carbon monoxide is a water soluble gas

Explanation

(a) In diamond, directional covalent bonds are present.
(b) Fullerenes are the pure forms of carbon.
(c) C-C bond length in layer of graphite is 141 pm.
Carbon monoxide is insoluble in water.
So, statement (b) is correct.
