Organic Chemistry 1 ACS Exam (2026/2027) |
Latest Questions | 100% Verified Answers | A+
• Constitutional Isomer -✓✓A compound with the same atoms but different atoms
bonded to each other
• Stereoisomers -✓✓Molecules with the same atoms differing only in 3D
configuration
• Enantiomers -✓✓Stereoisomers with exactly opposite stereochemical
designations at all stereogenic carbons
• Diasteriomers -✓✓Stereoisomers with several changes in the stereochemical
designations of stereogenic carbons (not completely opposite)
• R -✓✓Clockwise
• S -✓✓Counterclockwise
• cis -✓✓Same
• trans -✓✓Different
• E -✓✓Trans (in reference to alkenes)
• Z -✓✓Cis (in reference to alkenes)
, • Ortho -✓✓1,2 substitution
• Meta -✓✓1,3 substitution
• Para -✓✓1,4 substitution
• Protocol for naming esters -✓✓1) identify alkyl that is part of substituted alcohol
and use this first
2) identify alkyl on other side of carbonyl and use this as a second word, ending in
"-oate" (include carbonyl carbon)
• Benzyl vs. phenyl -✓✓Benzyl: ring + CH2
Phenyl: ring
• Aniline -✓✓Ring + NH2
• Protocol for naming substituted amides -✓✓1) first, name the substituted group
on the nitrogen
2) then, name the group on the other side of the carbonyl, ending in "-amide"
(including carbonyl carbon)
• What is the equation for Huckel's numbers? What are Huckel's numbers? -✓✓4n
+2
Huckel's numbers are the number of electrons in a pi system in aromatic
compounds
