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. Name for mathanal






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






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






4. How many stereoisomers can a molecule have with n chiral centers






5. Combustion reaction occurs through a radical process






6. Is bonded to only one other carbon atom






7. Methyl are 60 degrees apart. kinda stable






8. A molecule with an internal plane of symmetry






9. What is produced when o3 with lialh4 or nabh4






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






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






12. Carbon with four different substituents and lack a plane of symmetry






13. Common name for ethyne






14. Highest energy no separation. or 120 separation.






15. Diol with hydroxyl group on same carbon






16. Carbon carbon triple bonds. Suffix-yne.






17. Iso - neo - cyclo






18. Functionality is specified by alkoxy- prefix. ROR






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






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






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






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

23. Refers to the =CH2 group






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






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






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






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






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. N - l - ml - ms






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






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






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






33. 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-






34. Alphabetical order of alkane rxn






35. 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






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






37. Lowest priority group projects into the page






38. A = observed rotation / concentration * length






39. 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






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






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






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






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






44. Two hydroxyl groups






45. One s and two p 120 degree apart






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






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






48. Carbon double bonded to an oxygen






49. Charged - need electrons






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