The valency of carbon is generally 4, but its oxidation state may be -4, -2, 0, 2, -1 etc. In the compounds containing C, H and O, the oxidation number of C is calculated as
Oxidation number of C = \(\frac{2 \mathrm{n}_{\mathrm{O}}-\mathrm{n}_{\mathrm{H}}}{\mathrm{n}_{\mathrm{C}}}\)
where nO, nH, nC are the number of oxygen, hydrogen, and carbon atoms, respectively.
In which of the following compounds the oxidation state of C is 2?
  1. Ketenes
  2. Alkenes
  3. Allenes
  4. Carbenes

Answer

(D) Carbenes
