Chemical Bonding and Molecular Structure - Result Question 76
####78. 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
bond distance decreases as the multiplicity of the bond increases. Thus, bond distance decreases in the order: butane benzene > ethene (1.34) ethyne . Thus in butane, bond distance is the largest.
