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. 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






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






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






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






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






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






7. Functionality is specified by alkoxy- prefix. ROR






8. Sharing of electron between atoms






9. When bond angles deviate from ideal values






10. Lowest priority group projects into the page






11. 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






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






13. What are the best leaving groups?






14. One s and two p 120 degree apart






15. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






16. F - CL - Br - I






17. Alphabetical order of alkane rxn






18. 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-






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






20. One s and three p orbitals






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






22. Hydrocarbon with one or more carbon carbon triple bond






23. Refers to the =CH2 group






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






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






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






27. If reagent has a bunch of oxygen






28. Diol with hydroxyl group on same carbon






29. Monosubstituted ethylene






30. Steps of free radical substitution






31. A molecule with an internal plane of symmetry






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






33. Most favorable of staggared conformations






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






35. Same molecular formula but different structure






36. When boat flips






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






38. Charged - need electrons






39. Di - tri - t - sec - n -






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






41. M - chloroperoxybenzoic acid






42. 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






43. A sigma bond and two pi bonds






44. Combustion reaction occurs through a radical process






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






46. Two hydroxyl groups






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






48. Compounds with halogen






49. Name for ethanal






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