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






3. Name for mathanal






4. Carbon carbon triple bonds. Suffix-yne.






5. 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






6. 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






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






8. Same molecular formula but different structure






9. Methyl are 60 degrees apart. kinda stable






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






11. 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






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






13. Common name for ethyne






14. 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






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






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






17. Charged - need electrons






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






19. When boat flips






20. Two hydroxyl groups






21. 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.






22. Steps of free radical substitution






23. If reagent has a bunch of oxygen






24. One s and two p 120 degree apart






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






26. Not solvated






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






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






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






30. Name for propanal






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






32. Is bonded to only one other carbon atom






33. Object that is not superimposable upon mirror image






34. O3






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






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






37. Rotations cancel each other out therefore no optical activity






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






39. Electrons of pi bond are reactive and easily attacked by molecules that want e pair e.g. electrophiles.






40. Kmno4






41. A molecule with an internal plane of symmetry






42. Goal is to produce most stable carbocation


43. Transfer of electrions from one atome to another






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






45. 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.






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






47. Diol with hydroxyl group on same carbon






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






49. 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-






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