Lack of Reactivity of Benzene: Benzene only reacts with bromine (undergo electrophilic addition/ decolourise bromine) in presence of halogen carrier. The bond length C = C (single bond as in ethane) is 1.54 A and C = C double bond as in ethene is 1.33 A o. The Structure and Geometry of Benzene 1. C. 1. The double bonds may be localized in any position and therefore following resonating structures are possible : According to these structures, there should be three single bonds (bond length 154 pm) and three double bonds (bond length 134 pm) between carbon atoms in the benzene molecule. In general, the length of the bonds is a property of a whole molecule. 1. This picture is in complete accord with experiments which show that all carbon-carbon bonds in benzene are the same length, with no hint of shorter (double) or longer (single) bonds. Resonance is responsible for the stability of benzene. The answers given cover everything, but I want to make it more clear that the resonance effect mentioned by Abhijit means that the electrostatic forces on each carbon atom within the benzene molecule are exactly the same. In a simplified manner, the electrons who supposedly formed the 3 double bonds in the benzene ring are delocalised and thus each bond in benzene have the same length, you could say that they are 1.5 bonds instead of complete double bonds. The six-membered ring in benzene is a perfect hexagon (all carbon-carbon bonds have an identical length of 1.40 Å). Why is the length of the carbon-carbon bond of benzene shorter than the normal carbon-carbon bond? Using X- ray diffraction. A. The delocalized structure of benzene also accounts for the X-ray data (all C-C bond lengths equal) and the absence of the type of isomerism shown in Fig. D. 1. 3 4 A 0. Easy. No catalyst needed for alkenes. 43.1. The actual bond length (1.395 Å) is the intermediate between the sp 2 –sp 2 single bonds (1.46 Å) and double bonds (1.33 Å). The cyclohexatriene contributors would be expected to show alternating bond lengths, the double bonds being shorter (1.34 Å) than the single bonds … Bond length of C - C in benzene_____. The common practice of using only one of the Lewis structures is only to make keeping track of the π electrons easy. The carbon carbon bond length in benzene has been found to be 1.39A o which lies between single and double bond length value. Effectively bonds are in longer-shorter cycle, oscillating around some particular length. Lengths of C- C Bonds: Bond length of benzene in between bond length of C-C and C=C and all the C-C bonds are same length. B. Each bond in the benzene ring has the same number of electrons and is the same length. 5 4 A 0. 2 0 A 0. It means, that the distance between the same pair of atoms (e.g., C-H) may vary depending on … C-C bond length in benzene is 140 pm and C-H bond length is 109 pm. 3 9 A 0. Answer.
