Can you please check the chemical compounds. It is difficult to find them on tthe Internet. Thank you.

What is the appropriate expression to use in this context instead of give, or is give fine? I am also not sure about appropriate.

Sulphur compounds: mercaptans, dialkilsulphids, dialkildisulphids, naften sulphids and tiophens, with hydrogen and catalyst they give sulphurhydrogen and the appropriate hydrocarbon. Nitrogen compounds piridin, kinolin and pirol with hydrogen give ammonia and appropriate hydrocarbon.

'Give' is OK.Some of the chemical names need changing.

Sulphur compounds: mercaptans, dialkylsulphides, dialkyldisulphides, napthene sulphides and thiophenes, with hydrogen and catalyst, give hydrogen sulphide and the appropriate hydrocarbons. Nitrogen compounds: pyridine, quinoline and pyrrole with hydrogen give ammonia and the appropriate hydrocarbons.
Just in addition to Alan.es corrections:

a) mercaptanes,
b) they give the corresponding hydrocarbon
c) ammonia and the corresponding hydrocarbon.

No problem with 'corresponding hydrocarbons' - must be plural - good amendment.

However I don't agree that the plural given in (a) is correct, for me it's mercaptans.

Yes, you are right! I am buffled. There are alkanes, dithianes, boranes and spiranes -- but obviously mercaptans are an exception. Do you know any reason for this strange behaviour in English?

I'm not sure but I think the explanation is chemical rather than English.

There is only one mercaptan and all the others are derivatives of mercaptan whereas the alkanes, boranes, etc are families of compounds

Thank you very much.

Hm. I do not see the chemical point with regards to silane, borane, mercaptan. All do name a specific compound and can be used for the whole family. Mercaptans are used in plural exactly like boranes or silanes, too.

(alkane is indeed a class rather than a compound)
Is it because boranes and silanes as a class of compunds are analogous to the alkanes, whereas mercaptans, as a class of compounds, are analogous to alcohol with sulphur instead of oxygen?

We don't use alcoholes(sic).
