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. One s and two p 120 degree apart






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






3. Cleaves double bond in half - it only oxidizes the carbon to an aldehyde under reducing conditions. if ozidizing make same product as KMNO4






4. Compounds with halogen






5. Contain carbon carbon double bonds. Use same root of alkane but end with 'ene'






6. Occur when a molecule is broken down by heat. used to reduce the avverage molecular weight of heavy oils. c - c - bonds are cleave dand make small chain alkyl radicals that recombine to form different alkanes






7. Goal is to produce most stable carbocation

8. Carbon double bonded to an oxygen






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






10. Use the Greek root for the number of carbons followed by the ending - - ane






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






12. Rotations cancel each other out therefore no optical activity






13. Common name for ethyne






14. Object that is not superimposable upon mirror image






15. Same molecular formula but different structure






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






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






18. F - CL - Br - I






19. Zn/h or CH3/s with ozonolysis






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






21. Diols with hydroxyl group on adjacent carbon






22. M - chloroperoxybenzoic acid






23. 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






24. Steps of free radical substitution






25. N - l - ml - ms






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






27. What are the best leaving groups?






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

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






30. Functionality is specified by alkoxy- prefix. ROR






31. Electrons of pi bond are reactive and easily attacked by molecules that want e pair e.g. electrophiles.






32. Carbon carbon triple bonds. Suffix-yne.






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






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






35. Describes the exact spatial arrangement of groups of atoms independent of other molecules.






36. 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.






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






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






39. Not solvated






40. Name for propanal






41. Charged - need electrons






42. Highest energy no separation. or 120 separation.






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






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






45. Most favorable of staggared conformations






46. Nitrogen containing compound - longest chain attached to nitrogen used in backbone. use e and replace with AMINE. if more complex molecule present - use prefix amino. IF additional group added - use N-






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






48. Name for ethanal






49. Refers to the =CH2 group






50. Iso - neo - cyclo
