Methenyl is a hypothetical hydrocarbon radical CH, regarded as an essential residue of certain organic compounds while Methylene is a chemical species in which a carbon atom is bonded to two hydrogen atoms.
A methyl group consists of CH3 a methylene group is CH2
The "methyl" and "methylene" come from their chemical structures. Something that has "methyl" in its name contains a methyl group - CH3. A common chemical like this is methyl alcohol - CH3OH. The methylene group is CH2. The blue and violet? That's what color they are.
Absorption spectrum of methylene blue 665 nm
the difference is the addition of wintergreen oil or methyl salicylate to the clear version. It can be used to rub on sore muscles, etc.
The solubility difference between methyl alcohol (CH3OH) and benzene (C6H6) is related to the polar nature of methyl alcohol and the non polar nature of benzene. The OH group on methyl alcohol makes this a polar molecule and thus soluble in water. The lack of such a polar group in benzene makes it non polar, and thus insoluble in water.
Benzene - a six carbon, six hydrogen [planar] ring - C6H6 - has no side-groups. Yet when any one single side-hydrogen is replaced with one Methyl (-CH3) Group, we have Toluene. Short Answer = one methyl group.

The electron withdrawl from a proton by a neighbouring electronegative atom causes desheilding of proton. For eg. CH3CH2Cl Two signals are obtained For methyl and methylene protons. methyl protons are deshielded because it has a neighbouring electronegative methylene protons.while the methylene protons are shielded by chlorine atom. so the shielded methylene protons absorbs in down field.methyl protons- up field
Methylene chloride can be made simply by treating equal parts by weight of either methyl chloride or methane with chlorine gas at 400-500 °C
Methylene blue and methyl orange will have different binding affinities with the column material, and thus one will pass through the column more slowly than the other. This will result in one of the compounds being eluted from he column before the other. The one with the weakest binding to the column will be eluted first.
To prepare methylene blue indicator mix together some methylene blue with a naproxen solution. Then dilute with distilled water. If you would like your mixture to have a deeper blue color then add some juice from boiled cabbage.
i think the methylene blue will be make aqua blue because the charcoal will penerate the color of methylene blue,,,there are absorption process,,,in the charoal between the methylene blue.... (kharlz)
is methyl orange a pure substance
The ISO heet contains isopropyl alcohol and the other contains methyl alcohol

They would form some sort of brominated hydrocarbon of which there many varieties. The simplest among them are methyl bromide (CH3Br), methylene bromide (CH3Br2), and bromoform (CHBr3)
