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. Name for propanal






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






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






4. Monosubstituted ethylene






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






6. E of double bond act as lewis base and react with hydrogen of hx. make carbocation intermediate. use markonikovs rule






7. 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.






8. Combustion reaction occurs through a radical process






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






10. Charged - need electrons






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






12. A = observed rotation / concentration * length






13. A molecule with an internal plane of symmetry






14. A sigma bond and two pi bonds






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






16. Transfer of electrions from one atome to another






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






18. O3






19. 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-






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






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






22. Lowest priority group projects into the page






23. What is produced when o3 with lialh4 or nabh4






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






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






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






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






28. Functionality is specified by alkoxy- prefix. ROR






29. Not solvated






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. Two hydroxyl groups






32. Carbon carbon triple bonds. Suffix-yne.






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






34. 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






35. Differ in position of substitutents attached to a double bond or cycloalkane. Cis or trans or e or z






36. Diols with hydroxyl group on adjacent carbon






37. F - CL - Br - I






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






39. Kmno4






40. A radical transfers a hydrogen atom to another radical and makes an alkane and alkene






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






42. Rotations cancel each other out therefore no optical activity






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






44. Hydrocarbon with one or more carbon carbon triple bond






45. Steps of free radical substitution






46. One s and two p 120 degree apart






47. Formed by mixing different types of orbitals






48. Is bonded to only one other carbon atom






49. If reagent has a bunch of oxygen






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