(The correct prediction of this angle was an early success of ab initio quantum chemistry. [10]) However conversion to a linear configuration requires only 5.5 kcal/mol. [10] The singlet state has a slightly higher energy (by about 9 kcal/mol) than the triplet state, [10] and its H-C-H angle is smaller, about 102°. In dilute mixtures with an ...
Methylene is the simplest carbene.. In organic chemistry, a carbene is a molecule containing a neutral carbon atom with a valence of two and two unshared valence electrons.The general formula is R−:C−R' or R=C: where the R represents substituents or hydrogen atoms.
The hexamethylene diamine molecule contains six methylene groups. A methylene group is any part of a molecule that consists of two hydrogen atoms bound to a carbon atom, which is connected to the remainder of the molecule by two single bonds. [1]

In organic chemistry, methenium (also called methylium, carbenium, [2] methyl cation, or protonated methylene) is a cation with the formula CH + 3. It can be viewed as a methylene radical (: CH 2) with an added proton (H +), or as a methyl radical (• CH 3) with one electron removed.

The methylene bridge (methanediyl group) In organic chemistry, a methylene bridge, methylene spacer, or methanediyl group is any part of a molecule with formula −CH 2 −; namely, a carbon atom bound to two hydrogen atoms and connected by single bonds to two other distinct atoms in the rest of the molecule.
