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. N - l - ml - ms






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






3. One s and three p orbitals






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






5. 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-






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






7. Name for ethanal






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






9. M - chloroperoxybenzoic acid






10. When boat flips






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






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






13. 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.






14. Compounds with halogen






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






16. Name for propanal






17. When bond angles deviate from ideal values






18. Hydrocarbon with one or more carbon carbon triple bond






19. Carbon carbon triple bonds. Suffix-yne.






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






21. A sigma bond and two pi bonds






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






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






24. O3






25. F - CL - Br - I






26. Lowest priority group projects into the page






27. What are the best leaving groups?






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






29. Monosubstituted ethylene






30. Functionality is specified by alkoxy- prefix. ROR






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






32. Steps of free radical substitution






33. Methyl are 60 degrees apart. kinda stable






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






35. 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.






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






37. Carbon double bonded to an oxygen






38. One s and two p 120 degree apart






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






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






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






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






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






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






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






46. A = observed rotation / concentration * length






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






48. Not solvated






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






50. Charged - need electrons
