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






2. Iso - neo - cyclo






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






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






5. A molecule with an internal plane of symmetry






6. Alphabetical order of alkane rxn






7. A sigma bond and two pi bonds






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






9. When boat flips






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






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






12. Transfer of electrions from one atome to another






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






14. Object that is not superimposable upon mirror image






15. Use the Greek root for the number of carbons followed by the ending - - ane






16. Name for propanal






17. Diols with hydroxyl group on adjacent carbon






18. Monosubstituted ethylene






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






20. Combustion reaction occurs through a radical process






21. Formed by mixing different types of orbitals






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






23. Refers to the =CH2 group






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






25. N - l - ml - ms






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






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






28. 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.






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






30. Solvents with protons in solution - e.g. water or alcohol. large atoms tend to be better nucleophiles in here because they can shed the solvating protons around them and are more polarizable






31. Compounds with halogen






32. Carbon carbon triple bonds. Suffix-yne.






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






34. Sharing of electron between atoms






35. One s and two p 120 degree apart






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






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






38. F - CL - Br - I






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






40. Functionality is specified by alkoxy- prefix. ROR






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






42. Diol with hydroxyl group on same carbon






43. Name for ethanal






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






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






46. M - chloroperoxybenzoic acid






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






48. If reagent has a bunch of oxygen






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

50. 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.
