C. Single bonds tend to be longest and triple bonds shortest [i.e. C-C (154 pm), C=C (134 pm), C≡C (120 pm)]. The atoms must get closer to share more electrons.
Which C-C bond is the shortest?
C2H2 (ethyne or acetylene) due to presence of carbon-carbon triple bond has shortest carbon-carbon bond length.
What is the bond length of C triple bond C?
A typical carbon-carbon single bond has a length of 154 pm, while a typical double bond and triple bonds are 134 pm and 120 pm, respectively.
Which bond is longer C-C or C-C?
However, a C-C bond is longer than a C=C bond because, as the text says, "Multiple bonds are shorter than single bonds between the same two elements because the additional bonding electrons attract the nuclei more strongly and pull the atoms closer together (section 2.16, pg.
Which of the following cases C − C bond length will be highest?
Thus, it is found that the carbon-carbon bond diamond has the maximum bond length.
