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






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






3. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans






4. O3






5. Not solvated






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






7. N - l - ml - ms






8. Name for mathanal






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






10. Carbon carbon triple bonds. Suffix-yne.






11. Functionality is specified by alkoxy- prefix. ROR






12. Highest energy no separation. or 120 separation.






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






14. When boat flips






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






16. 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.






17. 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






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






19. Diol with hydroxyl group on same carbon






20. Rotations cancel each other out therefore no optical activity






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






22. Name for ethanal






23. Formed by mixing different types of orbitals






24. One s and three p orbitals






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






26. Most favorable of staggared conformations






27. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






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






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






30. Refers to the =CH2 group






31. Alphabetical order of alkane rxn






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






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






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






35. Methyl are 60 degrees apart. kinda stable






36. Lowest priority group projects into the page






37. Goal is to produce most stable carbocation

38. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






39. F - CL - Br - I






40. Same molecular formula but different structure






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






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






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






44. Common name for ethyne






45. M - chloroperoxybenzoic acid






46. 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.






47. A = observed rotation / concentration * length






48. 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






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






50. One s and two p 120 degree apart
