please label answers. thanks in advance
15. (2) a) Number the following acids in order of increasing acidity (weakest acid ? 1st): b) List the following bases in order of increasing basicity (weakest base ? first) NH3 NH2 H2O OH 16. (6) Based on approximate pKa values in Table 1, write products and predict if the equilibrium constant will be higher or less than 1: A) H2O+NH4^+ right arrow K B) OH + HCl right arrow K C) NH2 + HC=CH right arrow K 17. (2) What will be the major form for aminoacid alanine in solution with pH = 7 18. (2) Which is the strongest acid? 19) (2) Which of the following carbocations will NOT rearrange?Explanation / Answer
15.
a) trifluoroacetic acid > trichloro acetic acid > 3,3,3-trichloropropanoic acid > propanoic acid
b) NH2- > OH- > NH3 > H2O
16.
A) H2O + NH4+ ----> H3O+ + NH3 K < 1
B) OH- + HCl ---> H2O + Cl- K > 1
C) NH2- + HCCH ----> NH3 + HCC- K > 1
17) A
isoelectric point of alanine is at pH = 6.00
hence, at pH = 7, it exists as a base (structure a)
18. A
2.4.5-trinitrophenol is the strongest acid as the -I effect nd -R effect of the electron withdrawing nitro groups at ortho and para positions, increases the acidity of the compound.
19. B
structure B has no alkyl group on the carbon atom adjacent to the carbon bearing positive charge. hence, alkyl shift can't occur.
