Which one of these is NOT true for benzeneA. it forms only one type of monosbustituted productB. There are three carbon-carbon single bonds double bondsC. The heat of hydrogenation of benzene is less than the theoretical valueD. The bond angle between the carbon -carbon bonds is `120^@` |

Answer» Correct Answer - B Resonance gives each C-C bond in benzene some double bond character and this has been confimed by measuring bond length between two adjacent carbon atom in various compounds of benzene . The bond length C-C (`sigma` bond as in ethane) is 1.54 Å and C=C (double bond as in ethene ) is 1.33 Å.The carbon to carbon bond length in benzene has been found to be 1.39 Å which lies between single and double bond length values |
