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. Not solvated






2. Name for ethanal






3. A molecule with an internal plane of symmetry






4. Compounds with halogen






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






6. Diols with hydroxyl group on adjacent carbon






7. Formed by mixing different types of orbitals






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






9. Functionality is specified by alkoxy- prefix. ROR






10. If reagent has a bunch of oxygen






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






12. 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






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






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






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






16. Same molecular formula but different structure






17. Moleculse that have the opposite configuration at their one chiral center. or if multiple chiral centers - must have the opposite configuration at every one of their chiral centers to be enantiomers. identical physical properties and much of the same






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






19. Hydrocarbon with one or more carbon carbon triple bond






20. Refers to the =CH2 group






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






22. 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-






23. Zn/h or CH3/s with ozonolysis






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






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






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






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

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






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






30. Sharing of electron between atoms






31. Lowest priority group projects into the page






32. M - chloroperoxybenzoic acid






33. 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






34. Goal is to produce most stable carbocation

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






36. F - CL - Br - I






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






38. When boat flips






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






40. A sigma bond and two pi bonds






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






42. Carbon carbon triple bonds. Suffix-yne.






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






44. Iso - neo - cyclo






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






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






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






48. Most favorable of staggared conformations






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






50. Object that is not superimposable upon mirror image
