Their structures are illustrated using the xylenes (or dimethylbenzenes) in Figure 1. 75 mmol) in ethanol (20 ml). The Hock-rearrangement of hydroperoxides takes place essentially as the radical decomposition. Methylbenzene is more reactive than benzene because of the tendency of the methyl group to "push" electrons towards the ring. Consequently, the reaction conditions of the desiredproductwereexplored,theresultsdemonstrated. Preparation of aldehydes is possible by side chain halogenation, more specifically side chain chlorination, followed by hydrolysis. Ultraviolet – visible spectroscopy (λ 200 - 800 nm) studies the changes in electronic energy levels within the molecule arising due to transfer of electrons from π- or non-bonding orbitals. > Step 1: benzaldehyde + phenylmagnesium bromide → diphenylmethanol Step 2: diphenylmethanol + chromyl chloride → benzophenone You can use any reagent that converts a secondary alcohol to a ketone. It is a benzene derivative with the molecular formula C7H8. Methylbenzene is more reactive than benzene because of the tendency of the methyl group to "push" electrons towards the ring. With toluene on the other hand, the methyl group is electron-donating onto the benzene ring, so toluene extends the #p# orbital system all throughout the system, but sometimes the electrons are outside of the ring. Benzoic acid can be prepared from benzene molecule , converting it first methyl benzene or toluene by Friedel craft's alkylation reaction. Toluene was obtained in the yield of 96.
