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. F - CL - Br - I






2. Compounds with halogen






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






4. Carbon double bonded to an oxygen






5. 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-






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






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






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






9. Di - tri - t - sec - n -






10. Carbon carbon triple bonds. Suffix-yne.






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






12. Name for mathanal






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






14. One s and three p orbitals






15. When bond angles deviate from ideal values






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






17. Kmno4






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






19. Hydrocarbon with one or more carbon carbon triple bond






20. Object that is not superimposable upon mirror image






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






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






23. N - l - ml - ms






24. Not solvated






25. Formed by mixing different types of orbitals






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






27. Rotations cancel each other out therefore no optical activity






28. A sigma bond and two pi bonds






29. Charged - need electrons






30. Monosubstituted ethylene






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






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






33. 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






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






35. Name for propanal






36. 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.






37. 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






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






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






40. Steps of free radical substitution






41. Most favorable of staggared conformations






42. M - chloroperoxybenzoic acid






43. What is produced when o3 with lialh4 or nabh4






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






45. Same molecular formula but different structure






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






47. 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






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






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






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