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






3. Charged - need electrons






4. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






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






6. 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.






7. 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






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






9. Hydrocarbon with one or more carbon carbon triple bond






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






11. Refers to the =CH2 group






12. What is produced when o3 with lialh4 or nabh4






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






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






15. Methyl are 60 degrees apart. kinda stable






16. Diols with hydroxyl group on adjacent carbon






17. Alkenes oxidzed with kmno4 - if made with cold - dilue - make OH on each side of double bond - diols or glycol in syn orientation






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






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






20. Object that is not superimposable upon mirror image






21. Lowest priority group projects into the page






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






23. Transfer of electrions from one atome to another






24. Is bonded to only one other carbon atom






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






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






27. 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






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






29. Zn/h or CH3/s with ozonolysis






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






31. Common name for ethyne






32. 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-






33. Sharing of electron between atoms






34. Compounds with halogen






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






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






37. Functionality is specified by alkoxy- prefix. ROR






38. Two hydroxyl groups






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






40. Same molecular formula but different structure






41. Rotations cancel each other out therefore no optical activity






42. 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






43. M - chloroperoxybenzoic acid






44. Iso - neo - cyclo






45. Di - tri - t - sec - n -






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






47. Carbon double bonded to an oxygen






48. A sigma bond and two pi bonds






49. One s and two p 120 degree apart






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