Definition of heteroatom in English:



  • An atom in the ring of a cyclic compound other than a carbon atom.

    • ‘It has abundant carbon-containing molecules and heteroatoms.’
    • ‘The low order connectivity indices relate to fundamental parameters such as molecular surface area, molecular weight and the presence of heteroatoms.’
    • ‘Another common reaction, useful in the formation of ring systems containing a heteroatom such as nitrogen, is the hetero-Diels-Alder reaction.’
    • ‘The heteroatoms, including the retinal, were removed.’
    • ‘With only one heteroatom participating in resonance stabilization, the effect of the photolysis of the triarylmethanol on the binding constant will be maximal.’
