^ If the last character of the template input is }, MediaWiki will confuse it with the end-of-template tag }}. Adding a space between the two resolves this ambiguity. Other options include instead inserting {{null}} or <nowiki/>.

Formulas, charges, equations

संपादन करीं

Formulas (without charge) are just written:

  • {{chem2|CH3(CH2)5CH3}} → CH3(CH2)5CH3
  • {{chem2|Fe3S2(CO)9}} → Fe3S2(CO)9
  • {{chem2|C_{''n''}H_{2''n''+2}|}} → CnH2n+2

Charges are written inside parentheses:

  • {{chem2|SO4(2-)}} → SO2−4
  • {{chem2|S19(2+)}} → S2+19

Charges +1 and −1 can be written plain:

  • {{chem2|Na+}} → Na+
  • {{chem2|O2-}} → O−2
equals {{chem2|O2(-)}}

Chemical equations:

  • {{chem2|2 S + 3 O2 + 2 H2O -> 2 H2SO4}} → 2 S + 3 O2 + 2 H2O → 2 H2SO4
  • {{chem2|2S + 3O2 + 2H2O -> 2H2SO4}} → 2S + 3O2 + 2H2O → 2H2SO4

The arrows can be written as -> or just →. All characters (and unicode markup) are valid input except \, = (Mediawiki use it), _ and - (endash etc.)

  • {{chem2|2 H2_{(g)} + O2_{(g)} -> 2H2O_{(g)}|}} → 2 H2(g) + O2(g) → 2H2O(g)
  • {{chem2|NH2RCHCO2H <-> NH3+RCHCO2-}} → NH2RCHCO2H ⇌ NH+3RCHCO−2

Hapticity and mu:

  • {{chem2|W(CO)3(PiPr3)2(\h{2}H2)}} → W(CO)3(PiPr3)2(η2-H2)
  • {{chem2|auto=yes|W(CO)3(PiPr3)2(\h{2}H2)}} → W(CO)3(PiPr3)2(η2-H2)

Link the whole formula with |link=<wiki pagename>:

  • {{chem2|FeCl3|link=Iron(III) chloride}} → FeCl3

Or use wikilink brackets in input like [[ammonia|NH3]]:

  • {{chem2|3[[hydrogen|H2]] + 2[[nitrogen|N2]] <-> 2[[ammonia|NH3]]}} → 3H2 + 2N2 ⇌ 2NH3
संपादन करीं
Use |auto=yes to link each element symbol once, as well as some others such as Ph
  • {{chem2|CH3CH2CH3CBrFCIClCH3|auto=yes}} → CH3CH2CH3CBrFCIClCH3
संपादन करीं

Some common groups are recognized and linked if you wikilink them using [[ ]]

  • {{chem2|R\-[[COOH]]}} → R-COOH
  • {{chem2|[[CH3]]C[[R]]2[[I]]}} → CH3CR2I
  • In particular H2O links to water of crystallization in {{chem2|CuSO4 * 5 [[H2O]]}} → CuSO4 · 5 H2O, because a link to water is generally unnecessary.

You can link to any article even if chem2 is unaware of it:!-- same as |link=... then -->

To change the default link:

  • {{chem2|[[water|H2O]]}} → H2O
