MCQ
The $C-C$ bond length is maximum in
- Agraphite
- B$C_{70}$
- ✓diamond
- D$C_{60}$
✓
Answer
Correct option: C.
diamond
c
Since carbon in diamond is $sp^3$ hybridized and its $C -C$ bond order is $1$. In graphite and fullerene there is both $C -C$ and $C = C$ in conjugation, hence there is partial double bond character between carbon atoms
