English Dictionary

skeletal formula

名詞

(chemistry) A structural formula which is reduced (i.e., skeletal) in the sense that carbon atoms forming the backbone of the structure (esp. of an organic compound) are not labeled — they are shown simply as vertices — and hydrogen atoms are not shown at all (except those which are bonded to heteroatoms, or the exceptionally labeled carbon atoms) but heteroatoms are always labeled. (Labels of labeled hydrogen atoms are written next to labels of the atoms that they are bonded to, without a bond drawn between them. If there are several labeled hydrogen atoms bonded to the same atom then they are written as an H with a subscript for their number.) Carbon atoms which are (optionally) labeled tend to be in reactive extremities of the molecule, not the backbone of it.

日本語の意味

化学における骨格式。化合物の構造を示す際、炭素骨格は頂点として表され、炭素に結合する水素原子は通常省略され、異種原子は明示的に表示される簡略化された構造式である。

The chemist sketched the molecule's skeletal formula on the board to emphasize its carbon backbone.

化学者は分子の骨格式を黒板に描いて、その炭素骨格を強調した。
