Which of the following can act as a Lewis base?
A Lewis base is an electron-pair donor. N atoms have a valence of 5, and in the NH2NH2 compound, it is only bonded to another N atom and 2 H, so it's only using 3 of its 5 valence electrons to form these bonds. Thus, each nitrogen has a pair of unbonded electrons and can act as a Lewis base.
Compare your answer with the correct one above
Which of the following is a Lewis base?
NH3 should be the clear correct choice, since it is the only one having a pair of electrons that are available. The rest of the answer choices are all Lewis acids.
Compare your answer with the correct one above
In the following equation, which is the conjugate base of HClO4?
HClO4 + H2O → ClO4– + H3O+
The conjugate base of an acid will be the same compound, short one H atom. ClO4– is the only one that meets this criterion.

Which of the following is a Lewis base?
A Lewis base is an electron-pair donor. Only PH3 has a pair of nonbonding electrons and can act as a donor.
Compare your answer with the correct one above
Which of the following is the conjugate base of oxalic acid (H2C2O4)?
The conjugate base has one less H atoms and one unit greater negative charge because of this. Thus, the correct answer is HC2O4–
