H. K. T. Tetravalency of Oxygen. By J. F. Hetes (Phil. Mag. [5], 25, p. 221 — 237).
— The author considers that molecular compounds of haloid salts can be better
explained by supposing the haloids to be trivalent than by grouping the atoms ...
HCl, a remarkably stable body, we have a most striking case for the tetravalency
of oxygen, either as H\O/CH3 01/ \cH,' or, as seems preferable, CH CH H—01=O

Memorial Lectures Delivered Before the Chemical Society
Soc., 1865, 14, 198) claim to have anticipated Kekule's enunciation of the
tetravalency of carbon in a paper which they * published in 1857 (Annalen, 1857,

(i) Tetravalency: Carbon atom has electronic arrangement of 2, 4 which
represents the presence of 4 electrons in the valence shell. It requires 4 more
electrons to complete its octet. Therefore, carbon exhibits tetravalency. (ii)
Catenation: ...
