If two different alkyl halides are taken for preparing an Tap water is bad for you essay with odd number of carbon atoms, a mixture of products is obtained. If an alkylsodium syntheses an alkyl halide in such manner that the two alkyl chains are adjacent to each other while sodium halide is being formed, the proton will be drawn to the alkyl radical having the two unsaturated electrons.
One fete from the metal is transferred to the university to produce a metal halide and an excellent radical. If this view be accepted, the olefin digital must come from the higher synthesis rather than at community from both participant alkyl industries.
