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. M - chloroperoxybenzoic acid






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






3. 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






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






5. Diol with hydroxyl group on same carbon






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






7. Iso - neo - cyclo






8. 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






9. Functionality is specified by alkoxy- prefix. ROR






10. When boat flips






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






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






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






14. Two hydroxyl groups






15. Name for propanal






16. Rotations cancel each other out therefore no optical activity






17. 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






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






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






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






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






22. 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.






23. Carbon carbon triple bonds. Suffix-yne.






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






25. 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






26. What is produced when o3 with lialh4 or nabh4






27. Moleculse that have the opposite configuration at their one chiral center. or if multiple chiral centers - must have the opposite configuration at every one of their chiral centers to be enantiomers. identical physical properties and much of the same






28. Hydrocarbon with one or more carbon carbon triple bond






29. Carbon double bonded to an oxygen






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






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






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






33. Alphabetical order of alkane rxn






34. Name for ethanal






35. F - CL - Br - I






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






37. What are the best leaving groups?






38. Methyl are 60 degrees apart. kinda stable






39. Di - tri - t - sec - n -






40. Differ in position of substitutents attached to a double bond or cycloalkane. Cis or trans or e or z






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






42. Formed by mixing different types of orbitals






43. Lowest priority group projects into the page






44. O3






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






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






47. One s and two p 120 degree apart






48. 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-






49. If reagent has a bunch of oxygen






50. N - l - ml - ms
