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. Monosubstituted ethylene






2. 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.






3. Formed by mixing different types of orbitals






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






5. 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.






6. Object that is not superimposable upon mirror image






7. Name for propanal






8. Diol with hydroxyl group on same carbon






9. 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






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






11. Common name for ethyne






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






13. What are the best leaving groups?






14. 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






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






16. Same molecular formula but different structure






17. N - l - ml - ms






18. M - chloroperoxybenzoic acid






19. Di - tri - t - sec - n -






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






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






22. When bond angles deviate from ideal values






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






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






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






26. Is bonded to only one other carbon atom






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






28. A = observed rotation / concentration * length






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






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






31. Two hydroxyl groups






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






33. Not solvated






34. What is produced when o3 with lialh4 or nabh4






35. Refers to the =CH2 group






36. Lowest priority group projects into the page






37. If reagent has a bunch of oxygen






38. Carbon double bonded to an oxygen






39. 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-






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






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






42. Iso - neo - cyclo






43. Diborane add to double bond. boron acts as lewis acid and attaches to less hindered carbon. hydride transferred to adjacent carbon. antimarkonikov - alcohol produced






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






45. Highest energy no separation. or 120 separation.






46. Spatial arrangement of the atoms or groups of a sterioisomer






47. Zn/h or CH3/s with ozonolysis






48. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






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






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