The pBlock Elements - Result Question 25
####26. In graphite, electrons are
[1993, 1994]
(a) Localised on every third $C$-atom
(b) Present in anti-bonding orbital
(c) Localised on each $C$-atom
(d) Spread out between the structure
Show Answer
Solution:
- (d) In graphite, each carbon is $s p^{2}$-hybridized and the single occupied unhybridized $p$-orbital of $C$-atoms overlap side ways to give $\pi$-electron cloud which is delocalized and thus the electrons are spread out between the structure.
