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. 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






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






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






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






5. Object that is not superimposable upon mirror image






6. Formed by mixing different types of orbitals






7. Steps of free radical substitution






8. 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-






9. M - chloroperoxybenzoic acid






10. Combustion reaction occurs through a radical process






11. Iso - neo - cyclo






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






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






14. Alphabetical order of alkane rxn






15. Diol with hydroxyl group on same carbon






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






17. Carbon carbon triple bonds. Suffix-yne.






18. Di - tri - t - sec - n -






19. Name for propanal






20. Most favorable of staggared conformations






21. 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






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






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






24. 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.






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






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






27. Kmno4






28. N - l - ml - ms






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






30. Carbon double bonded to an oxygen






31. Same molecular formula but different structure






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






33. Name for mathanal






34. Lowest priority group projects into the page






35. Is bonded to only one other carbon atom






36. Charged - need electrons






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






38. Results when nonadjacent atoms or groups compete for space. dominant source of energy in flagpole interactions of the boat conformation. thus it goes in various conformations like chair boat and twist.






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






40. Sharing of electron between atoms






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






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






43. Zn/h or CH3/s with ozonolysis






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






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






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






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






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






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






50. A sigma bond and two pi bonds
