MCAT Organic Chemistry

Subjects : mcat, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. When two atomic orbitals combine. obtained mathematically by adding or subtracting wave functions. if sings are the same - make bonding - if different - less stable antibonding.






2. Methyl are 60 degrees apart. kinda stable






3. Rotations cancel each other out therefore no optical activity






4. Alkenes oxidzed with kmno4 - if made with cold - dilue - make OH on each side of double bond - diols or glycol in syn orientation






5. Name for ethanal






6. In which one or morehydrogen atoms are replaced with a halogen atom. via free radical substitution






7. Combustion reaction occurs through a radical process






8. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






9. N - l - ml - ms






10. When two p orbitals line up in parallel and electron clouds overlap. it exsits over a single bond.






11. Configuration in relation to another chiral molecule. use it to determine if a molecule is an enantiomer - diastereomer - etc






12. Alphabetical order of alkane rxn






13. If a compound is able to rotate plane polarized light.






14. Arise from angle strain - torsional strian and nonbonded strain






15. F - CL - Br - I






16. Ozonolysis under hot acidic kmO4 - e.g. H2O2 condition






17. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






18. Name for mathanal






19. M - chloroperoxybenzoic acid






20. Always receive number one. contain carbonyl and OH group - very oxidized. highest priority functional group.






21. Spatial arrangement of the atoms or groups of a sterioisomer






22. Most favorable of staggared conformations






23. One s and three p orbitals






24. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






25. Carbon with four different substituents and lack a plane of symmetry






26. O3






27. If reagent has a bunch of oxygen






28. Results when cyclic molecules must assume conformations that have eclipsed interactions






29. Creation of long - high molecular weight polymer composed of repeating subunit called monomers. occur through a radical mechanism.






30. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.

31. Same chemical formula. same atomic connectivity . different in how atoms are arranged in space






32. Results when nonadjacent atoms or groups compete for space. dominant source of energy in flagpole interactions of the boat conformation. thus it goes in various conformations like chair boat and twist.






33. Di - tri - t - sec - n -






34. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






35. E of double bond act as lewis base and react with hydrogen of hx. make carbocation intermediate. use markonikovs rule






36. When bond angles deviate from ideal values






37. Most similar. same molecule only at different points in their rotation. show them with newmans projections






38. Propylenes attached to a backbone at the C-3 position. Meaning the double bond at end of the chain and single bonded carbon at rest






39. Kmno4






40. Charged - need electrons






41. How many stereoisomers can a molecule have with n chiral centers






42. Formed by mixing different types of orbitals






43. Reaction of alkane with oxygen to form carbon dioxide - water and heat.






44. Highest energy no separation. or 120 separation.






45. Object that is not superimposable upon mirror image






46. Sharing of electron between atoms






47. Chain of carbons connected by single bonds with hydrogen atoms attached.






48. Diol with hydroxyl group on same carbon






49. Carbon carbon triple bonds. Suffix-yne.






50. Non mirror image of configurational isomers. cis and trans alkenes are them. possible when a molecule has two or more stereogenic centers that differ at some but not alll of the centers. they require multiple chiral centers.
