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






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






3. F - CL - Br - I






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






5. Rotations cancel each other out therefore no optical activity






6. One s and two p 120 degree apart






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






8. If reagent has a bunch of oxygen






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






10. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






11. Formed by mixing different types of orbitals






12. Zn/h or CH3/s with ozonolysis






13. Two p orbital form pi and third p orbital combine with s to make two sp hybrid. 180 degree apart






14. When a molecular orbital is formed head to head or tail to tail. all single bonds are tehese.






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

16. Water can be added to alkenes under acidic conditions. make carbocation. ends with alcohol






17. A radical transfers a hydrogen atom to another radical and makes an alkane and alkene






18. Compounds with halogen






19. Methyl are 60 degrees apart. kinda stable






20. Is bonded to only one other carbon atom






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






22. Nonsuperimposable mirror image of chiral objects - a specific steroisomer.






23. Carbon double bonded to an oxygen






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






25. Refers to the =CH2 group






26. 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






27. Sharing of electron between atoms






28. Combustion reaction occurs through a radical process






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






30. Hydrocarbon with one or more carbon carbon triple bond






31. Alphabetical order of alkane rxn






32. Same molecular formula but different structure






33. Monosubstituted ethylene






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






35. Charged - need electrons






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






37. When bond angles deviate from ideal values






38. Carbonyl located at the end of the chain named by replacing al with e. e.g. butanal






39. Name for ethanal






40. When boat flips






41. 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.






42. Diborane add to double bond. boron acts as lewis acid and attaches to less hindered carbon. hydride transferred to adjacent carbon. antimarkonikov - alcohol produced






43. What are the best leaving groups?






44. Solvents with protons in solution - e.g. water or alcohol. large atoms tend to be better nucleophiles in here because they can shed the solvating protons around them and are more polarizable






45. Carbon carbon triple bonds. Suffix-yne.






46. Lowest priority group projects into the page






47. Diol with hydroxyl group on same carbon






48. No double bonds. it has the maximum number of hydrogens.






49. Nucleus lover. electron rich species that are attracked to charged atoms






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