WebThe triangular structure of cyclopropane requires the bond angles between carbon-carbon covalent bonds to be 60°. The molecule has D 3h molecular symmetry. The C-C distances are 151 pm versus 153-155 pm. [15] [16] Despite their shortness, the C-C bonds in cyclopropane are weakened by 34 kcal/mol vs ordinary C-C bonds. WebCyclopropane is the smallest cyclic hydrocarbon. Because its 60 degree bond angles reduce orbital overlap, its bonds are weak. As a result, it is thermally unstable and rearranges to propene at 1000 degrees Celsius via the following first-order reaction: (k = 9.2 s^-2) what is the half life of the reaction? d-- 0.075s detective richard omiecinski https://techmatepro.com
