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. M - chloroperoxybenzoic acid






2. Zn/h or CH3/s with ozonolysis






3. O3






4. Alphabetical order of alkane rxn






5. If reagent has a bunch of oxygen






6. Steps of free radical substitution






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






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






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






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






11. Rotations cancel each other out therefore no optical activity






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






13. Goal is to produce most stable carbocation

14. 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-






15. 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






16. Reaction of alkane with oxygen to form carbon dioxide - water and heat.






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






18. Monosubstituted ethylene






19. 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






20. When bond angles deviate from ideal values






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






22. Formed by mixing different types of orbitals






23. N - l - ml - ms






24. F - CL - Br - I






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






26. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






27. Compounds with halogen






28. Carbon double bonded to an oxygen






29. Name for propanal






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






31. Two hydroxyl groups






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






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






34. Iso - neo - cyclo






35. Refers to the =CH2 group






36. Carbon carbon triple bonds. Suffix-yne.






37. A molecule with an internal plane of symmetry






38. What is produced when o3 with lialh4 or nabh4






39. 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.






40. 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






41. Lowest priority group projects into the page






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






43. 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






44. A sigma bond and two pi bonds






45. Name for mathanal






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






47. Not solvated






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






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






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