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. Methyl are 60 degrees apart. kinda stable






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






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






5. F - CL - Br - I






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






7. A = observed rotation / concentration * length






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






9. Most favorable of staggared conformations






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






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






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






13. What are the best leaving groups?






14. Diols with hydroxyl group on adjacent carbon






15. Iso - neo - cyclo






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






17. One s and three p orbitals






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






19. Sharing of electron between atoms






20. M - chloroperoxybenzoic acid






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






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






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






24. Nonsuperimposable mirror image of chiral objects - a specific steroisomer.






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






26. Is bonded to only one other carbon atom






27. A molecule with an internal plane of symmetry






28. When boat flips






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






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






31. Goal is to produce most stable carbocation

32. What is produced when o3 with lialh4 or nabh4






33. Di - tri - t - sec - n -






34. 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-






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






36. 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.






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






38. Carbon carbon triple bonds. Suffix-yne.






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






40. Transfer of electrions from one atome to another






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






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






43. One s and two p 120 degree apart






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






45. Combustion reaction occurs through a radical process






46. Compounds with halogen






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






48. If reagent has a bunch of oxygen






49. O3






50. A sigma bond and two pi bonds
