Problem- I want to make cis-2-pentene given propyne and other reagents as needed. I need to use retrosynthesis to get from my starting material (propyne) to my target material (cis-2-pentene).
HClO is a weak acid (Ka = 4.0 × 10-8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.087 M in NaClO?
