LaTeXation complete

[edit]

I think we should include some examples, since the formula is being written for everyone.

I typeset the formula. However, wouldn't it make more sense to represent it in this simplified version?

I agreed so I changed it. Isopropyl 21:40, 8 April 2006 (UTC)[reply]

[edit]

I had 4 good ones on there, where did they go? AStudent

Oxygens, Nitrogens, Halides

[edit]

Don't these affect the degree of unsaturation?142.58.43.188 (talk) 17:09, 22 October 2008 (UTC)[reply]

halides do, oxygen and nitrogen don't. i've changed it.--75.62.179.247 (talk) 02:28, 30 November 2008 (UTC)[reply]

Yes! Where is the nitrogens? The description in the article confuses reader how to count the nitrogens. -- (talk) 14:44, 8 December 2008 (UTC)[reply]
Now the article ignores nitrogens and other trivalent atoms. I suggest the following formula: where is the number of atoms with valence . For example, in the formula CnHx, we have the DU as 1 + (n(4-2) + x(1-2))/2 = 1 + (2n-x)/2, which gives the same result as the current formula. Bbi5291 (talk) 00:50, 14 January 2009 (UTC)[reply]
