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






3. 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-






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

5. 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.






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






7. Zn/h or CH3/s with ozonolysis






8. Not solvated






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






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






11. Rotations cancel each other out therefore no optical activity






12. A molecule with an internal plane of symmetry






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






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






15. Carbon double bonded to an oxygen






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






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






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






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






20. Charged - need electrons






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. Lowest priority group projects into the page






23. 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.






24. Goal is to produce most stable carbocation

25. Highest energy no separation. or 120 separation.






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






27. 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






28. Refers to the =CH2 group






29. 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






30. Compounds with halogen






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






32. 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






33. F - CL - Br - I






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






35. Steps of free radical substitution






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






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






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






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






40. Most favorable of staggared conformations






41. N - l - ml - ms






42. What is produced when o3 with lialh4 or nabh4






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






44. Diol with hydroxyl group on same carbon






45. Formed by mixing different types of orbitals






46. A = observed rotation / concentration * length






47. Is bonded to only one other carbon atom






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






49. When boat flips






50. M - chloroperoxybenzoic acid
