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






2. Name for mathanal






3. What are the best leaving groups?






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






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






6. Iso - neo - cyclo






7. M - chloroperoxybenzoic acid






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






9. Compounds with halogen






10. Two hydroxyl groups






11. A sigma bond and two pi bonds






12. Highest energy no separation. or 120 separation.






13. Not solvated






14. 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






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

16. Results when cyclic molecules must assume conformations that have eclipsed interactions






17. Name for propanal






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






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






20. 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






21. Transfer of electrions from one atome to another






22. One s and two p 120 degree apart






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






24. Monosubstituted ethylene






25. 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-






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






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






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






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






30. Kmno4






31. Hydrocarbon with one or more carbon carbon triple bond






32. 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.






33. Common name for ethyne






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






35. When bond angles deviate from ideal values






36. One s and three p orbitals






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






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






39. Functionality is specified by alkoxy- prefix. ROR






40. Most favorable of staggared conformations






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






42. Combustion reaction occurs through a radical process






43. A = observed rotation / concentration * length






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






45. Charged - need electrons






46. Object that is not superimposable upon mirror image






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






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






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






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