In 1st ion, negative charge is on Oxygen atom
In 2nd ion, negative charge is on Nitrogen atom
The more electronegative the atom, greater is electron holding capacity and hence electron donating tendency is less and hence that will be a weaker base.
Oxygen is more electronegative that Nitrogen and because of this the ion with negative charge on Oxygen is weaker base.

Question 8 3 pts Which of the following is not a conjugate acid/base pair? O HC2H302/C2H302" O NH4+/NH3 CO2/C03 OH3PO4/H2PO4 Question 9 3 pts A 1.0 M solution of NaC2H3O2 in water is expected to be: Acidic because sodium acetate undergoes hydrolysis Neutral because sodium acetate is a salt Basic because acetate ion is the conjugate base of acetic acid Acidic because it forms acetic acid Question 10 3 pts Examples of ionizing radiation would include: infrared (IR) visible light...
Question 1 1 pts Why is it important for DNA to have complementary base pairing? O Complementary base pairing allows base pairs to be packed in the most energetically favorable arrangement inside of the double helix structure. O Complementary base pairing will pair a purine with a purine, which are a similar width, thus they are able to hold the sugar-phosphate backbone an equal distance apart along the DNA molecule o Complementary base pairing is only important for maintaining the...
