nomenclature
« on: August 11, 2005, 05:30:18 PM »
I've been using serch strings .. "methyl methylene CH3 CH2 CH nomenclature" etc. but there was no answer to what is probably a stupid question..  :-\

If CH3 is methyl, CH2 is methylene .. what the hell is CH & C?

methyl methylene? if it exists, it must be a radical.

H3C-CH2

the carbon atom in bold contains an unpaired valence electron. this qualifies the molecule methyl methylene a radical. In fact, it's a secondary radical.

Unless that went stright over my head, that wasnt the question :-X

methyl = CH3
methylene = CH2
??? = CH

why are you learning outdated organic nomenclature? we all now follow the IUPAC standard.

C would be carbon I imagine.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

-CH3 ---> methyl radical

-CH2- ---> methylene radical

=CH- ---> methine radical
 
=C= ---> carbon atom
