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. F - CL - Br - I






2. Object that is not superimposable upon mirror image






3. Zn/h or CH3/s with ozonolysis






4. Functionality is specified by alkoxy- prefix. ROR






5. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.

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






7. One s and three p orbitals






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






9. Di - tri - t - sec - n -






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






11. Compounds with halogen






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






13. Steps of free radical substitution






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






15. What are the best leaving groups?






16. A = observed rotation / concentration * length






17. Kmno4






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






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. Combustion reaction occurs through a radical process






21. Most similar. same molecule only at different points in their rotation. show them with newmans projections






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






23. Rotations cancel each other out therefore no optical activity






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






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






26. Name for ethanal






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






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






29. One s and two p 120 degree apart






30. O3






31. Carbon carbon triple bonds. Suffix-yne.






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






33. Lowest priority group projects into the page






34. Monosubstituted ethylene






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






37. Diols with hydroxyl group on adjacent carbon






38. A molecule with an internal plane of symmetry






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






40. 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.






41. Arise from angle strain - torsional strian and nonbonded strain






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






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






44. Not solvated






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






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






47. 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






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






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






50. If reagent has a bunch of oxygen
