wedged bond : projects towards viewer dashed bond : projects away from viewer isomers : Two different molecules that have the same chemical formula conformational isomers : same molecule rotated differently around a bond structural (constitutional) isomers : compounds with same molecular formula but have different connectivity of atoms 2 | P a g e Stereoisomers : molecules that have the same structural formulas and bonding patterns but different arrangements of atoms in space t...

isomers Correct Answer: same molecular formula, different structure another name for structural isomers Correct Answer: conSTItutional isomers constitutional vs. conformational isomers Correct Answer: constitutional/structural isomers: same molecular formula, DIFFERENT connectivity conformational isomers: SAME connectivity, but are interconverted by rapid rotation about a sigma bond giving temporary shapes of molecules, of varying energies aliphatic compound Correct Answer: non-...
