MCQ
The number and type of bonds between two carbon atoms in $CaC_2$ are
- AOne $\sigma -$ and one $\pi -$ bond
- ✓One $\sigma -$ and two $\pi -$ bond
- COne $\sigma -$ and half $\pi -$ bond
- DOne $\sigma -$ bond
✓
Answer
Correct option: B.
One $\sigma -$ and two $\pi -$ bond
b
The number and type of bonds between two carbon atoms in $CaC _2$ are one sigma $(\sigma)$ and two pi $(\pi)$-bonds and ionic bonds between $Ca ^{+2}$ ion and carbide ion. $C _2^{2-}$ has $[ C \equiv C ]^{2-}$ structure.
