A laboratory route to 2- and 4-chlorotoluene proceeds from 2- and 4-toluidines (i.e. 2- and 4-aminotoluene). These compounds are diazotized followed by treatment with cuprous chloride. [1] Industrially, the diazonium method is reserved for 3-chlorotoluene. The industrial route to 2- and 4-chlorotoluene entails direct reaction of toluene with ...

Chloromethyl methyl ether (CMME) is a compound with formula CH 3 OCH 2 Cl. A colorless liquid, it is a chloroalkyl ether.It is used as an alkylating agent.In organic synthesis, it is used for introducing the methoxymethyl ether (MOM) protecting group, [3] and is thus often called MOM-Cl or MOM chloride.
1,2,3-Trichlorobenzene is an organochlorine compound with the chemical formula C 6 H 3 Cl 3. [ 1 ] [ 2 ] This is one of three isomers of trichlorobenzene ; the two others are 1,2,4-Trichlorobenzene and 1,3,5-Trichlorobenzene .
Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.
(Techniques have also been devised for generating heteronuclear correlation spectra, in which the two axes correspond to different isotopes, such as 13 C and 1 H.) Diagonal peaks correspond to the peaks in a 1D-NMR experiment, while the cross peaks indicate couplings between pairs of nuclei (much as multiplet splitting indicates couplings in 1D ...
The physical properties of the isomers of xylene differ slightly. The melting point ranges from −47.87 °C (−54.17 °F) (m-xylene) to 13.26 °C (55.87 °F) (p-xylene)—as usual, the para isomer's melting point is much higher because it packs more readily in the crystal structure. The boiling point for each isomer is around 140 °C (284 °F).
