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. Functionality is specified by alkoxy- prefix. ROR






2. Carbon double bonded to an oxygen






3. Diol with hydroxyl group on same carbon






4. 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






5. Diols with hydroxyl group on adjacent carbon






6. Name for ethanal






7. M - chloroperoxybenzoic acid






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






9. One s and two p 120 degree apart






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






11. Steps of free radical substitution






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






13. Methyl are 60 degrees apart. kinda stable






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






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






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






17. Compounds with halogen






18. Iso - neo - cyclo






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






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






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






22. Di - tri - t - sec - n -






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






24. 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.






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






26. 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.






27. Charged - need electrons






28. O3






29. Name for mathanal






30. Same molecular formula but different structure






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






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






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






34. 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






35. Rotations cancel each other out therefore no optical activity






36. Transfer of electrions from one atome to another






37. Most favorable of staggared conformations






38. Y = position of double bond - x is position of triple bond - root is the prefix representing the length of the principal carbon chain






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






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






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






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






43. What are the best leaving groups?






44. 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






45. Carbon carbon triple bonds. Suffix-yne.






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






47. A molecule with an internal plane of symmetry






48. Is bonded to only one other carbon atom






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






50. Name for propanal
