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. 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






2. Monosubstituted ethylene






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






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






5. Diol with hydroxyl group on same carbon






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






7. Name for ethanal






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






9. When boat flips






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






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






12. Steps of free radical substitution






13. What are the best leaving groups?






14. A sigma bond and two pi bonds






15. Iso - neo - cyclo






16. A molecule with an internal plane of symmetry






17. When bond angles deviate from ideal values






18. Charged - need electrons






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






20. Rotations cancel each other out therefore no optical activity






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






22. Carbon double bonded to an oxygen






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






24. What is produced when o3 with lialh4 or nabh4






25. Name for propanal






26. Lowest priority group projects into the page






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






28. Is bonded to only one other carbon atom






29. Formed by mixing different types of orbitals






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






31. 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.






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






33. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






34. Methyl are 60 degrees apart. kinda stable






35. 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






36. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






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






38. F - CL - Br - I






39. N - l - ml - ms






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






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






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






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






44. Kmno4






45. 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






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






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






48. Combustion reaction occurs through a radical process






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






50. Sharing of electron between atoms
