...In chemistry, isomers are compounds with the same molecular formula but different structural formulas. The word is derived from the Greek ισομερης, isomerès; isos = "equal", méros = "part". There are many different classes of isomers, like stereoisomers, enantiomers, geometrical isomers, et cetera (see chart below). Isomers do not necessarily share similar properties, unless they also have the same functional groups. There are two main forms of isomerism: structural isomerism and stereoisomerism (spatial isomerism). Read full entry

How do you know if it has If it asks draw all the
isomers of (for example) a
tetrahedral or octahedral
molecule, how do you know
which isomer has an optical
isomer. How do you know
whether a structure also has
an optical isomer. I know that
if they are not superimposable
then they are isomers, but I
can't really tell that by
looking at a drawing on a
paper so what is an easier way
to tell if there is an optical
isomer?
This is mainly for
coordination compounds by the
way.

Correct way to draw a lewis I am trying to draw the lewis
structure for N2O. I am
wondering if the correct way
to draw it would be:
N-N-O or N-O-N (not including
the actual number of bonds and
e-)
I'm thinking that it should be
the first one and that the
second one is a structural
isomer. Is this correct?
Thank you for your help!

Miss Brittney, You are correct: N-N-O, 100%. See link down below (nice work!). There are resonance structures, but while the N-O-N structure seems plausible, it does not go down that way. The link shows the resonance structures. Hope that helped! |
