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. Diols with hydroxyl group on adjacent carbon






3. A = observed rotation / concentration * length






4. Goal is to produce most stable carbocation

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






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






7. Combustion reaction occurs through a radical process






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






9. Iso - neo - cyclo






10. What are the best leaving groups?






11. When bond angles deviate from ideal values






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






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






14. A sigma bond and two pi bonds






15. Name for propanal






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






17. Charged - need electrons






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






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






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






21. N - l - ml - ms






22. 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-






23. 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






24. Sharing of electron between atoms






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






26. A molecule with an internal plane of symmetry






27. Name for ethanal






28. Two hydroxyl groups






29. 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.






30. Carbon carbon triple bonds. Suffix-yne.






31. Same molecular formula but different structure






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






33. Is bonded to only one other carbon atom






34. Refers to the =CH2 group






35. Transfer of electrions from one atome to another






36. O3






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






38. Zn/h or CH3/s with ozonolysis






39. 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






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






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






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






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






44. Hydrocarbon with one or more carbon carbon triple bond






45. Diol with hydroxyl group on same carbon






46. Spatial arrangement of the atoms or groups of a sterioisomer






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






48. Monosubstituted ethylene






49. Di - tri - t - sec - n -






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