Chemical Bonding and Molecular Structure - Result Question 80
####82. Which structure is linear ?
(a) $SO_2$
(b) $CO_2$
(c) $CO_3^{2-}$
(d) $SO_4^{2-}$
[1992]
Show Answer
Solution:
- (b) $CO_2$ has $s p$-hybridization and is linear. $SO_2$ and $CO_3^{2-}$ are planar $(s p^{2})$ while $SO_4^{2-}$ is tetrahedral $(s p^{3})$.
