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. Refers to the =CH2 group






2. Alphabetical order of alkane rxn






3. O3






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






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






6. A sigma bond and two pi bonds






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






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






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






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






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






13. Formed by mixing different types of orbitals






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






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

16. 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






17. Steps of free radical substitution






18. Lowest priority group projects into the page






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






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






21. Highest energy no separation. or 120 separation.






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






23. Diol with hydroxyl group on same carbon






24. Carbon double bonded to an oxygen






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






26. E of double bond act as lewis base and react with hydrogen of hx. make carbocation intermediate. use markonikovs rule






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






28. A = observed rotation / concentration * length






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






30. A molecule with an internal plane of symmetry






31. 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






32. Rotations cancel each other out therefore no optical activity






33. M - chloroperoxybenzoic acid






34. Carbon carbon triple bonds. Suffix-yne.






35. Results when nonadjacent atoms or groups compete for space. dominant source of energy in flagpole interactions of the boat conformation. thus it goes in various conformations like chair boat and twist.






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






37. Not solvated






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






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






40. One s and three p orbitals






41. Same molecular formula but different structure






42. 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






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






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






45. Zn/h or CH3/s with ozonolysis






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






47. Name for propanal






48. Monosubstituted ethylene






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






50. Name for mathanal
