CHOOSE the compound which has a highest for each property: (question #9 to 19) 9. Boiling Point: OH (B) 10. Solubility in Water: OH (B) OH (C) 11. Solubility in Hexane: OH (D) 12. Base Strength: (A)) (By OH (C) N112 :0-CH, (D) 13. The Strength of Nucleophile: (A) e011 (B) Ho (D) SCH3 14. Sy1 Reactivity in a Protic Solvent: CI Br (B) Br 15. Sy2 Reactivity in an Aprotic Solvent: CI (D) 16. Electrophylic Substitution Reactivity: (B) c (D) Br HO 17. Polar Solvent: 18. Priority Group in Stereochemistry: (A) NO2 B)f (D) SO,H (C) SH 19. The Strength of Oxidizer: (A) PCC (C) KMnO,/HSO (D) HNO, (B) H2SO4Explanation / Answer
Q9
the OH group will have higher point, so ignore B and D
the total amount of carbons in C is higher, therefore, expect higher BP in C
Q10
solubility depends on amount of OH- an dipoles
the less C-H chain bonded to a single OH the better
the best is D, sicne there are only CH3CH2OH present
Q11
solubility of hexane requires polar compounds
from all, only B has "nonpolar" compound, i.e. C-H bonds
Q12
base strnegh = accept H+
from the list;
alkanes will readily accept H+ from solution,
Q13
nucleophile strenght depends mainly on how well they accept eletrophiles
form th elist, the best is D
