Chemical Bonding and Molecular Structure - Result Question 52
####53. Considering the state of hybridization of carbon atoms, find out the molecule among the following which is linear?
[2011]
(a) $CH_3-CH=CH-CH_3$
(b) $CH_3-C \equiv C-CH_3$
(c) $CH_2=CH-CH_2-C \equiv CH$
(d) $CH_3-CH_2-CH_2-CH_3$
Show Answer
Solution:
- (b) $H_3 C-C \equiv C-\stackrel{s p}{CH_3}$ linear
It is important to note that in but-2-yne, the hydrogen atoms are not linear.
$ \begin{aligned} & H \backslash s p^{3} s p^{3} s p^{3} s p^{3} X H \\ & H-C-C \equiv C-C-H \\ & H \end{aligned} $
