Want this question answered?
Nt sure I agree with the question. Consider the octahedral polyatomic ion Co(NH3)4Cl2+ this has trans and cis isomers (chlorines opposite each other at 180 0 or next to each other at 90 0). Generelly isomerism is rare in electrovalent compounds. One interesting example is the optical isomerism of ammonium sodium tartrate discovered by Pasteur.
unsymmetrical atom & chiral carbonoptical isomers=2nmesomers=osymmetrical atom & chiral carbon- 1,3,5,...optical isomers=2n-1mesomers=2n/2-1symmetrical atom & chiral carbon- 2,4,6,...optical isomers=2n-1-2(n-1)/2mesomers=2(n-1)/2
The carbonyl group present in aldehydes or ketones itself is optically inactive but if a carbon attached to carbonyl group is asymmetric (attached to four different groups or atoms) then such compound may show to enantiomers as there are two enantiomers of CH3-CHCl-CHO.
Free-electron lasers were invented at Stanford University by John Madey. While these lasers share the same optical properties as conventional lasers, the main difference between the two is the principal they use to form the beam.
L and D amino acids are both optical isomers of each other and only differ in their ability to rotate plane polarized light in opposite directions.
optical path = μ x geometricalpath
ofcourse optical zoom..................
All mirages are optical illusions but all optical illusions are not mirages.

The difference between optical and non optical is the way the drive in the DVD reads the disk. Optical is a better and more higher quality reader. So the picture is much better.
light is must for optical microscope while is not necessary for nonn optical one
Glycine because it is not chiral :)

No, it is NOT either both. Besides 'benzenepropanol' is not an official name.
Alkynes always form a triple bond. This being so, essentially, all you have are the two carbon molecules and the triple bond! No matter what way your turn it, or how you look at it, even if in a mirror (ie. optical isomerism) you will always have the same looking molecule while to have a geometrical isomer cis or trans form should be there. gen equation for a compound to be a geometrica isomer: 1.YXC = CXY 2.YXC = CXZ
