Isomer

Science / Chemistry / Isomer: Molecules with identical molecular formulas but different structural formulas.

Geometric Isomer

Science / Chemistry / Geometric Isomer: Geometric isomers are molecules that have the same molecular formula and bond connections, but distinctly different shapes. MORE

Stereoisomer

Science / Chemistry / Stereoisomer: Molecules with the same atoms and bond structure, but different three dimensional arrangements of atoms. For example, the CH3 groups in CH3CH=CHCH3 can be placed on the same side of the double bond in MORE

Isomerization

Science / Chemistry / Isomerization: A chemical change that involves a rearrangement of atoms and bonds within a molecule, without changing the molecular formula. MORE

Amphi

Science / Chemistry / Amphi: A prefix used to name certain members of a series of geometric isomers or stereoisomers. MORE

Allo

Science / Chemistry / Allo: A prefix that designates the more stable of a pair of geometric isomers. allo- is sometimes used less precisely to designate isomers or close relatives of a compound. MORE

Racemic

Science / Chemistry / Racemic: A mixture of equal parts of the levorotatory and dextrorotatory isomers of the the same substance. Racemic mixtures are not optically active. MORE
