Chemical Bonding And Molecular Structure Ques 104
104. The distance between the two adjacent carbon atoms is largest in
[1994]
(a) benzene
(b) ethene
(c) butane
(d) ethyne
Show Answer
Solution:
- (c) The $C-C$ bond distance decreases as the multiplicity of the bond increases. Thus, bond distance decreases in the order: butane $(1.54 \AA)$ $>$ benzene $(1.39 \AA)$ > ethene (1.34) $\AA>$ ethyne $(1.20 \AA)$. Thus in butane, $C-C$ bond distance is the largest.
