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






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






3. Is bonded to only one other carbon atom






4. Two hydroxyl groups






5. Highest energy no separation. or 120 separation.






6. One s and three p orbitals






7. A sigma bond and two pi bonds






8. Methyl are 60 degrees apart. kinda stable






9. 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






10. Carbon double bonded to an oxygen






11. Charged - need electrons






12. Name for ethanal






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






14. Goal is to produce most stable carbocation

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






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






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






18. Refers to the =CH2 group






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






20. 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.






21. Functionality is specified by alkoxy- prefix. ROR






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






23. 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






24. Compounds with halogen






25. Carbon carbon triple bonds. Suffix-yne.






26. M - chloroperoxybenzoic acid






27. Diol with hydroxyl group on same carbon






28. Object that is not superimposable upon mirror image






29. 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.






30. Rotations cancel each other out therefore no optical activity






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






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






33. Zn/h or CH3/s with ozonolysis






34. Combustion reaction occurs through a radical process






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






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






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






38. Sharing of electron between atoms






39. Most favorable of staggared conformations






40. 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-






41. N - l - ml - ms






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






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






44. Diols with hydroxyl group on adjacent carbon






45. What is produced when o3 with lialh4 or nabh4






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






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






48. When bond angles deviate from ideal values






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






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