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. M - chloroperoxybenzoic acid






2. 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.






3. Contain carbon carbon double bonds. Use same root of alkane but end with 'ene'






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






5. Name for mathanal






6. Lowest priority group projects into the page






7. Charged - need electrons






8. Combustion reaction occurs through a radical process






9. Refers to the =CH2 group






10. Rotations cancel each other out therefore no optical activity






11. Name for ethanal






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






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






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






15. Kmno4






16. A sigma bond and two pi bonds






17. If reagent has a bunch of oxygen






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






19. Highest energy no separation. or 120 separation.






20. O3






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






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






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






24. Diol with hydroxyl group on same carbon






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






26. Moleculse that have the opposite configuration at their one chiral center. or if multiple chiral centers - must have the opposite configuration at every one of their chiral centers to be enantiomers. identical physical properties and much of the same






27. Hydrocarbon with one or more carbon carbon triple bond






28. What is produced when o3 with lialh4 or nabh4






29. Sharing of electron between atoms






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






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






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






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






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






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






36. F - CL - Br - I






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






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






39. Goal is to produce most stable carbocation

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






41. 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






42. Iso - neo - cyclo






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






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






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






46. Name for propanal






47. Formed by mixing different types of orbitals






48. When boat flips






49. Compounds with halogen






50. When bond angles deviate from ideal values
