Concept Introduction:
ISOMERS:
The molecules which have the same molecular formula but different arrangement of atom are called as isomers. There are two types of isomers,
- Structural isomers
- Stereo isomers
Structural isomers:
A molecules with same chemical formulas but differ structurally in the sequence in which the atoms are linked are called as structural or constitutional isomers.
Stereo isomers:
Stereo isomers are the isomers that have same molecular formula but differ in spatial arrangement of atoms. Stereo isomers can be sub divided into two groups,
- Optical isomers
- Geometric isomers
Optical isomers:
Optical isomers are the mirror image of a molecule and they can be rotated by plane polarized light.
Geometric isomers:
If there is restricted rotation in a molecule there arises geometric isomerism. Geometric isomers are also known as Cis- Trans isomerism.
- If the two atoms locked in same side of the molecule then it is called as cis isomers.
- If the two atoms locked in opposite side of the molecule then it is called as trans isomers.

General Chemistry
- A mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forwardPLEASE HELP ! URGENT!arrow_forward
