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. Lowest priority group projects into the page






2. Charged - need electrons






3. Zn/h or CH3/s with ozonolysis






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






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






6. Diols with hydroxyl group on adjacent carbon






7. Most favorable of staggared conformations






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






9. 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






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






11. Name for ethanal






12. 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






13. 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.






14. A = observed rotation / concentration * length






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






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






17. Refers to the =CH2 group






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






20. Occur when a molecule is broken down by heat. used to reduce the avverage molecular weight of heavy oils. c - c - bonds are cleave dand make small chain alkyl radicals that recombine to form different alkanes






21. Formed by mixing different types of orbitals






22. Carbon double bonded to an oxygen






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






24. What are the best leaving groups?






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






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






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






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






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






30. Compounds with halogen






31. Functionality is specified by alkoxy- prefix. ROR






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






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






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






35. Steps of free radical substitution






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






37. O3






38. When bond angles deviate from ideal values






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






40. Goal is to produce most stable carbocation

41. Object that is not superimposable upon mirror image






42. Carbon carbon triple bonds. Suffix-yne.






43. If reagent has a bunch of oxygen






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






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






46. Common name for ethyne






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






48. What is produced when o3 with lialh4 or nabh4






49. 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-






50. Not solvated
