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






2. One s and three p orbitals






3. Compounds with halogen






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






5. Steps of free radical substitution






6. Diols with hydroxyl group on adjacent carbon






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






8. 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






9. A = observed rotation / concentration * length






10. Name for mathanal






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






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






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






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






15. Zn/h or CH3/s with ozonolysis






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






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






18. Diol with hydroxyl group on same carbon






19. 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






20. 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






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






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






23. Carbon carbon triple bonds. Suffix-yne.






24. F - CL - Br - I






25. Lowest priority group projects into the page






26. Most favorable of staggared conformations






27. 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.






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






29. When bond angles deviate from ideal values






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






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






32. When boat flips






33. Iso - neo - cyclo






34. O3






35. Two hydroxyl groups






36. Monosubstituted ethylene






37. M - chloroperoxybenzoic acid






38. Same molecular formula but different structure






39. Transfer of electrions from one atome to another






40. Common name for ethyne






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






42. A molecule with an internal plane of symmetry






43. What is produced when o3 with lialh4 or nabh4






44. N - l - ml - ms






45. Not solvated






46. Highest energy no separation. or 120 separation.






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






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






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






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