The decyl "chain" as shown in formulas 5 through 9 is termed a "straight chain", as one carbon follows another, like the links of a chain. Structures 15 or 16 are termed "branched chains". [An illustration of the formulas follows.] The overall formula for 5-7, C₁₀H₂₁Cl, is the same. Formulas 5-7 each represents "decyl chloride." However 15 and 16 differ in a crucial way. The difference is that formulas 15 and 16 have two "CH₃" groups near the left end of the molecule. This is seen more easily in 17, a "condensed formula" that is equivalent to the "line formula" 15. Furthermore, 15 to 17 have a single "CH" group present, whereas 7 has no "CH" groups, only "CH₃" and "CH₂" groups.

The rubber hydrocarbon is a chemical compound composed of two elements, carbon and hydrogen, and having the general formula(C_5sub>H8) n. The rubber hyrdrocarbon is present in latex as a suspension of minute particles varying in size from 4 to 20 millionths of an inch(0. 1-0. 5 micrometer). The largest particles can be viewed under the ultramicroscope and are seen to be in constant motion, exhibiting the phenomenon known as Brownian movement.  2, record 26, English, - rubber%20hydrocarbon</sub>

A selectively labelled compound may be multiply labelled when in the unmodified compound there is more than one atom of the same element at the position where the isotopic modification occurs, e. g., H in CH₄, or there are several atoms of the same element at different positions where the isotopic modification occurs, e. g., C in C₄ H_8</sub> O.  1, record 27, English, - multiply%20labelled

Whereas in an aromatic molecule there is continuous overlap of p-orbitals over a cyclic array of atoms, in a homoaromatic molecule there is a formal discontinuity in this overlap resulting from the presence of a single sp³ hybridized atom within the ring; p-orbital overlap apparently bridges this sp³ centre, and features associated with aromaticity are manifest in the properties of the compound. Pronounced homoaromaticity is not normally associated with neutral molecules, but mainly with species bearing a formal electrical charge, e. g., the "homotropylium" cation C₈ H_9</sub>⁺...  1, record 28, English, - homoaromatic

Tandis que dans une molécule aromatique il y a recouvrement continu des orbitales p tout au long d'un ensemble cyclique d'atomes, une molécule homoaromatique comporte une discontinuité formelle due à la présence d'un atome d'hybridation sp³ [et d'un seul) au sein du cycle. Apparemment, le recouvrement des orbitales p crée un pont entre les atomes de carbone adjacents au centre sp³ et l'on observe pour le composé des propriétés caractéristiques, associées à l'aromaticité. Normalement, on n'observe pas d'homoaromaticité prononcée pour des molécules neutres; elle apparaît principalement pour des espèces portant une charge électrique formelle, par exemple pour le cation "homotropylium" C₈ H₉ [...]  1, record 28, French, - homoaromatique

The transformation of unstable sodium sulfide(Na₂S) to the more stable sodium thiosulfate(Na₂S₂O₃) in black liquor by the use of air or oxygen(O₂) so that objectionable hydrogen sulfide(H_2</sub>S) and organic sulfur compound formation in its evaporation and combustion are minimized, thus preventing their loss from the sulfate recovery process.
