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:

  1. (d) In graphite, each carbon is sp2-hybridized and the single occupied unhybridized p-orbital of C-atoms overlap side ways to give π-electron cloud which is delocalized and thus the electrons are spread out between the structure.
