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






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






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






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






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






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

7. Methyl are 60 degrees apart. kinda stable






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






9. Is bonded to only one other carbon atom






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






11. Alphabetical order of alkane rxn






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






13. F - CL - Br - I






14. Compounds with halogen






15. One s and three p orbitals






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






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






18. Object that is not superimposable upon mirror image






19. Diborane add to double bond. boron acts as lewis acid and attaches to less hindered carbon. hydride transferred to adjacent carbon. antimarkonikov - alcohol produced






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






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






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






23. Diols with hydroxyl group on adjacent carbon






24. 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






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






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






27. Two hydroxyl groups






28. Lowest priority group projects into the page






29. 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-






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






31. Functionality is specified by alkoxy- prefix. ROR






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






33. Not solvated






34. Rotations cancel each other out therefore no optical activity






35. Sharing of electron between atoms






36. Combustion reaction occurs through a radical process






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






38. Hydrocarbon with one or more carbon carbon triple bond






39. Name for propanal






40. Same molecular formula but different structure






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. Diol with hydroxyl group on same carbon






43. What is produced when o3 with lialh4 or nabh4






44. 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






45. What are the best leaving groups?






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






47. One s and two p 120 degree apart






48. A molecule with an internal plane of symmetry






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






50. Refers to the =CH2 group
