Which outcome occurs when electron pairing fails within graphene's pi system?

A)Increased electrical resistance develops
B)Enhanced thermal conductivity appears
C)Mechanical strength becomes enhanced
D)Optical transparency abruptly vanishes

💡 Explanation

Increased electrical resistance develops through electron localization because disruption of *conjugated pi-system delocalization* prevents coherent electron movement. Therefore mobility drops drastically, rather than increasing conductivity, because mobile electrons are necessary.
