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. Zn/h or CH3/s with ozonolysis






2. Charged - need electrons






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






4. Is bonded to only one other carbon atom






5. Sharing of electron between atoms






6. Name for propanal






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






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






9. 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-






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






11. Not solvated






12. What are the best leaving groups?






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






14. 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






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






16. Iso - neo - cyclo






17. A sigma bond and two pi bonds






18. Diol with hydroxyl group on same carbon






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






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






21. Goal is to produce most stable carbocation

22. Most favorable of staggared conformations






23. Alphabetical order of alkane rxn






24. 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






25. Formed by mixing different types of orbitals






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






27. Diols with hydroxyl group on adjacent carbon






28. One s and two p 120 degree apart






29. Name for ethanal






30. When bond angles deviate from ideal values






31. Same molecular formula but different structure






32. Lowest priority group projects into the page






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






34. When boat flips






35. Steps of free radical substitution






36. If reagent has a bunch of oxygen






37. Carbon carbon triple bonds. Suffix-yne.






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






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






40. Two hydroxyl groups






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






42. Hydrocarbon with one or more carbon carbon triple bond






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






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

45. O3






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






47. Kmno4






48. Compounds with halogen






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






50. Rotations cancel each other out therefore no optical activity
