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. Hydrocarbon with one or more carbon carbon triple bond






2. Di - tri - t - sec - n -






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






4. Transfer of electrions from one atome to another






5. One s and three p orbitals






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






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






8. 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






9. 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






10. Same molecular formula but different structure






11. Charged - need electrons






12. Most favorable of staggared conformations






13. What is produced when o3 with lialh4 or nabh4






14. 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-






15. One s and two p 120 degree apart






16. When bond angles deviate from ideal values






17. Alphabetical order of alkane rxn






18. Not solvated






19. Monosubstituted ethylene






20. When boat flips






21. 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






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






23. Highest energy no separation. or 120 separation.






24. A molecule with an internal plane of symmetry






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






26. A = observed rotation / concentration * length






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






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






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






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






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






32. Name for ethanal






33. Compounds with halogen






34. 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






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






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






37. Diol with hydroxyl group on same carbon






38. Steps of free radical substitution






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






40. Object that is not superimposable upon mirror image






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






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






43. Kmno4






44. Two hydroxyl groups






45. Name for propanal






46. If reagent has a bunch of oxygen






47. Refers to the =CH2 group






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






49. F - CL - Br - I






50. Combustion reaction occurs through a radical process
