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






2. 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






3. If reagent has a bunch of oxygen






4. Functionality is specified by alkoxy- prefix. ROR






5. Iso - neo - cyclo






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






7. When bond angles deviate from ideal values






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






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






10. Kmno4






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






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






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






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






15. Carbon double bonded to an oxygen






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






17. Combustion reaction occurs through a radical process






18. Steps of free radical substitution






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






20. Alphabetical order of alkane rxn






21. Name for propanal






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






23. Name for ethanal






24. Common name for ethyne






25. 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






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






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






28. Charged - need electrons






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. Is bonded to only one other carbon atom






31. Name for mathanal






32. Methyl are 60 degrees apart. kinda stable






33. 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






34. Most favorable of staggared conformations






35. Sharing of electron between atoms






36. Diol with hydroxyl group on same carbon






37. A = observed rotation / concentration * length






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






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






40. One s and two p 120 degree apart






41. Refers to the =CH2 group






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






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






44. 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






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






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






47. One s and three p orbitals






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






49. 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






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