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






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






3. Share molecular formula but have different chemical and physical properties






4. Compounds with halogen






5. N - l - ml - ms






6. Charged - need electrons






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






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

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






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






11. Methyl are 60 degrees apart. kinda stable






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






13. 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.






14. Two hydroxyl groups






15. Object that is not superimposable upon mirror image






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






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






18. If reagent has a bunch of oxygen






19. What is produced when o3 with lialh4 or nabh4






20. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans






21. Same molecular formula but different structure






22. More likely it is to attract positively charged proton. nucleophilic strength decreses: RO->HO>RCO2>ROH>H2O






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






24. When bond angles deviate from ideal values






25. 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






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






27. Rotations cancel each other out therefore no optical activity






28. Name for propanal






29. F - CL - Br - I






30. Name for ethanal






31. Transfer of electrions from one atome to another






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






33. 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.






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






35. 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-






36. Name for mathanal






37. Sharing of electron between atoms






38. Carbon double bonded to an oxygen






39. Most favorable of staggared conformations






40. Not solvated






41. Iso - neo - cyclo






42. Highest energy no separation. or 120 separation.






43. A = observed rotation / concentration * length






44. A molecule with an internal plane of symmetry






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






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






47. M - chloroperoxybenzoic acid






48. 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






49. Carbonyl located in middle or somewhere in chane. Named with One






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