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. Zn/h or CH3/s with ozonolysis






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






3. M - chloroperoxybenzoic acid






4. Transfer of electrions from one atome to another






5. Lowest priority group projects into the page






6. Sharing of electron between atoms






7. Diols with hydroxyl group on adjacent carbon






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






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






10. 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






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






12. When bond angles deviate from ideal values






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






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






15. Goal is to produce most stable carbocation


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






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






18. Not solvated






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






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






21. Rotations cancel each other out therefore no optical activity






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






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






24. Two hydroxyl groups






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






26. Carbon double bonded to an oxygen






27. Carbonyl located at the end of the chain named by replacing al with e. e.g. butanal






28. What is produced when o3 with lialh4 or nabh4






29. Same molecular formula but different structure






30. Ozonolysis under hot acidic kmO4 - e.g. H2O2 condition






31. 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.






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






33. N - l - ml - ms






34. 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






35. Most favorable of staggared conformations






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






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






38. When boat flips






39. Methyl are 60 degrees apart. kinda stable






40. Hydrocarbon with one or more carbon carbon triple bond






41. Kmno4






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






43. Name for mathanal






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






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






46. Steps of free radical substitution






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






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






49. A sigma bond and two pi bonds






50. Alphabetical order of alkane rxn
