Question

Strengths as bases:
H2O, F-, Cl-, NO,, and CN-
​

Answer 1

Cl^-<NO3^-<H2O<F^-<CN^-

Step-by-step explanation:

When we talk about base strength we are referring to how easily a chemical specie accepts protons.

The greater the ability of a specie to accept H^+, the greater its base strength.

The order of increasing base strengths of the species listed are shown in the answer above.
