To understand why all C-C bonds in benzene are of equal length, we can break down the explanation into several steps:Step 1: Structure of Benzene Benzene is a cyclic hydrocarbon with the formula C₆H₆. It consists of six c
in isolated condition C−C bond length of C2H4 is x than the bond length ofn C−C bond of C2H4 in Zeise 's salt is . A Greater thanx B Less than x C Equal to x D None of these Video Solution Play Video Text SolutionVerified by Experts The correct Answer is:B Due to synergic...
The most important method for determining the C—C bond length in polycyclic hydrocarbons is X-ray analysis. When applied to benzene the length of a hexagon side was found to be 1·392 .1 If benzene were formed by the superimposition of the two Kekulé structures, a value half-way between...
Bond length is largely influenced by the type of covalent bond- single, double, or triple- found between two atoms. How do you determine bond length? One easy way for determining bond length is to draw the structure using a Lewis diagram and to analyze this structure for the type of ...
The microwave spectrum of the benzene isomer 3,4-dimethylenecyclobutene including spectra of all possible single 13C-substituted and sufficient singly and doubly D-substituted species to give a complete r5 geometry, have been measured and analysed. An estimate of the re geometry has also been deri...
Latin longus (source of prolong, elongate, longitude, etc.) thus is probably cognate with, but not the source of, the Germanic words. The word illustrates the Old English tendency for short "a" to become short "o" before -n- (also retained in bond/band and West Midlands dialectal lond...

Although experimental molecular structure is one of the oldest and most frequently applied diagnostic tools in studies of the nature of chemical bonds, it is concluded that its application to all but the grossest details of bonds such as carbon-carbon bonds remains entirely speculative. The concept...
Some rodent species adjust their basal body temperature (Tb) in response to day length, independent of external temperature. For instance, mean Tb of Siberian hamsters maintained at 23 °C in SD is 0.7 °C lower than mean Tb of LD hamsters housed at the same temperature (Heldmaier et al....
