这个说法更加准确。它强调了CH₂作为一个基团(functional group)在有机化学中的作用。它就像一个“积木块”,可以和其他“积木块”组合,构建各种各样的有机分子。 但是,网上那些关于CH₂的毒性描述,让我觉得有点问题。它说CH₂会引起皮肤、粘膜刺激,甚至肺炎。这说法不太严谨。CH₂本身不会单独存在,它必须...
Conversely, when the terminal methyl group of butyronitrile (or its isocyanide isomer) is replaced by F or Cl, the stability trends are reversed and the anti conformer becomes slightly more stable than the gauche one. These changes in relative stabilities could be traced through an analysis of ...

Energy Analysis of Metal-Ligand Bonding in Transition Metal Complexes with Terminal Group-13 Diyl Ligands (CO)4Fe-ER, Fe(EMe)5 and Ni(EMe)4 (E = B−Tl; R... The metal-ligand bonds of the title compounds have been investigated with the help of an energy partitioning analysis at the...
For reactions CF3CH2OCHF2 + OH/Cl, the calculation indicates that the hydrogen abstraction from CH2 group is the dominant reaction channel, and the displacement processes may be negligible because of the high barriers. The standard enthalpies of formation for the reactant CF3CH2OCHF2, and two...
PH-functional methylenbisphosphanes RR′P-CH 2 -PRH (R′=R, H) are versatile ligands in coordination chemistry. They may oxidatively add with their PH-bonds to transition metals in low oxidation numbers and form cluster compounds with P-C-P-bridges. P-C-P-bond cleavage reactions afford...
Functional Group: Functional groups constitute a class of atoms inside a molecule that possesses identical chemical attributes whenever it emerges in several compounds. Some functional groups possessing oxygen include alcohol and ether. Answer and Explanation: ...
