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. Diol with hydroxyl group on same carbon






2. Compounds with halogen






3. 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






4. Hydrocarbon with one or more carbon carbon triple bond






5. Highest energy no separation. or 120 separation.






6. Not solvated






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






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






9. Name for ethanal






10. 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.






11. O3






12. 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






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






14. Diols with hydroxyl group on adjacent carbon






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






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






17. M - chloroperoxybenzoic acid






18. Object that is not superimposable upon mirror image






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






20. F - CL - Br - I






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






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






23. A = observed rotation / concentration * length






24. Methyl are 60 degrees apart. kinda stable






25. Goal is to produce most stable carbocation

26. Charged - need electrons






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






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






29. Creation of long - high molecular weight polymer composed of repeating subunit called monomers. occur through a radical mechanism.






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






31. Iso - neo - cyclo






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

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






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






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






36. Formed by mixing different types of orbitals






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






38. Electrons of pi bond are reactive and easily attacked by molecules that want e pair e.g. electrophiles.






39. Same molecular formula but different structure






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






41. Carbon carbon triple bonds. Suffix-yne.






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






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






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






45. When boat flips






46. Is bonded to only one other carbon atom






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






48. Functionality is specified by alkoxy- prefix. ROR






49. 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-






50. Combustion reaction occurs through a radical process
