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. Di - tri - t - sec - n -






2. What are the best leaving groups?






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






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






5. Is bonded to only one other carbon atom






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






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






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






9. Refers to the =CH2 group






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






11. 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






12. F - CL - Br - I






13. Highest energy no separation. or 120 separation.






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






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






16. O3






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






18. Not solvated






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






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






21. Two hydroxyl groups






22. 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-






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






24. When boat flips






25. Methyl are 60 degrees apart. kinda stable






26. Lowest priority group projects into the page






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






28. 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






29. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






30. Zn/h or CH3/s with ozonolysis






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






32. Name for mathanal






33. Results when cyclic molecules must assume conformations that have eclipsed interactions






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






35. Transfer of electrions from one atome to another






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

37. One s and three p orbitals






38. Formed by mixing different types of orbitals






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






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






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






42. Compounds with halogen






43. Same molecular formula but different structure






44. Steps of free radical substitution






45. M - chloroperoxybenzoic acid






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






47. Combustion reaction occurs through a radical process






48. Common name for ethyne






49. Goal is to produce most stable carbocation

50. Carbon carbon triple bonds. Suffix-yne.
