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






2. Name for mathanal






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






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






5. What is produced when o3 with lialh4 or nabh4






6. Steps of free radical substitution






7. M - chloroperoxybenzoic acid






8. Arise from angle strain - torsional strian and nonbonded strain






9. Zn/h or CH3/s with ozonolysis






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






11. When bond angles deviate from ideal values






12. Combustion reaction occurs through a radical process






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






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






15. Goal is to produce most stable carbocation

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






17. N - l - ml - ms






18. Rotations cancel each other out therefore no optical activity






19. Functionality is specified by alkoxy- prefix. ROR






20. 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






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






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






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






24. A = observed rotation / concentration * length






25. Kmno4






26. Most favorable of staggared conformations






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






28. A molecule with an internal plane of symmetry






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






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






31. Two hydroxyl groups






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






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

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






35. 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.






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






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






38. Diols with hydroxyl group on adjacent carbon






39. Carbon carbon triple bonds. Suffix-yne.






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






41. Formed by mixing different types of orbitals






42. Transfer of electrions from one atome to another






43. Name for ethanal






44. Highest energy no separation. or 120 separation.






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






46. Iso - neo - cyclo






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






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






49. Alkenes oxidzed with kmno4 - if made with cold - dilue - make OH on each side of double bond - diols or glycol in syn orientation






50. Common name for ethyne
