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. 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






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






3. When bond angles deviate from ideal values






4. Combustion reaction occurs through a radical process






5. One s and three p orbitals






6. Carbon double bonded to an oxygen






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






8. If reagent has a bunch of oxygen






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






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






11. Name for propanal






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






13. A = observed rotation / concentration * length






14. Object that is not superimposable upon mirror image






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






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






17. Transfer of electrions from one atome to another






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






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






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

21. Lowest priority group projects into the page






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






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






24. Is bonded to only one other carbon atom






25. Formed by mixing different types of orbitals






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






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






28. 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.






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






30. Hydrocarbon with one or more carbon carbon triple bond






31. One s and two p 120 degree apart






32. Name for ethanal






33. F - CL - Br - I






34. Common name for ethyne






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






36. When boat flips






37. Same molecular formula but different structure






38. Compounds with halogen






39. Not solvated






40. Highest energy no separation. or 120 separation.






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






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






43. 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






44. Iso - neo - cyclo






45. Carbonyl located in middle or somewhere in chane. Named with One






46. What is produced when o3 with lialh4 or nabh4






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






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






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






50. 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-
