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. A sigma bond and two pi bonds






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






3. One s and three p orbitals






4. Highest energy no separation. or 120 separation.






5. Same molecular formula but different structure






6. Most favorable of staggared conformations






7. When bond angles deviate from ideal values






8. 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.






9. F - CL - Br - I






10. Non mirror image of configurational isomers. cis and trans alkenes are them. possible when a molecule has two or more stereogenic centers that differ at some but not alll of the centers. they require multiple chiral centers.






11. Object that is not superimposable upon mirror image






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






13. Iso - neo - cyclo






14. What are the best leaving groups?






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






16. Name for ethanal






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






18. Name for mathanal






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






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






21. Formed by mixing different types of orbitals






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






23. Name for propanal






24. O3






25. Describes the exact spatial arrangement of groups of atoms independent of other molecules.






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






27. Combustion reaction occurs through a radical process






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






29. Sharing of electron between atoms






30. Functionality is specified by alkoxy- prefix. ROR






31. 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






32. Transfer of electrions from one atome to another






33. Di - tri - t - sec - n -






34. Compounds with halogen






35. Alphabetical order of alkane rxn






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






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






38. Not solvated






39. 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






40. N - l - ml - ms






41. Two hydroxyl groups






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






43. Rotations cancel each other out therefore no optical activity






44. Is bonded to only one other carbon atom






45. When boat flips






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






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

48. Carbon carbon triple bonds. Suffix-yne.






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






50. Diol with hydroxyl group on same carbon
