hydrogen halides / haloalkanes Explanation: Halides are compounds of halogens, elements in Group 7 /17 of the periodic table: fluorine, chlorine, bromine iodine. In this instance, the gases being referred to are likely to be the hydrogen compounds which are all gaseous at room temperature and hazardous to various extents. The term may also be used for haloalkanes, also known as alkyl halides (including freons) but suspect the former applies here because of the implied nature of the hazard. References online at many levels, have cited a straightforward one for each -------------------------------------------------- Note added at 22 hrs (2014-08-08 15:54:10 GMT) -------------------------------------------------- Either or both of the suggested replacements may be appropriate. However, the more general term of the original (meaning given in first line of explanation) may have been used for a reason. Cannot say which without wider context. Please check the chemistry before deciding whether / how to amend.
