Answer:

Both have a pH greater than 7, but NH₃ has a lower pH than KOH.

Explanation:

  • Both of NH₃ and KOH are bases (can produce OH⁻), so both have a pH greater than 7.
  • NH₃ is considered as a weak base (not completely ionized), while KOH is a strong base (completely ionized).
  • If both NH₃ an KOH has the same concentration, KOH produces OH⁻ higher than that of NH₃.
  • So, NH₃ has a lower pH than KOH.

  • Thus the right choice is:

<em>Both have a pH greater than 7, but NH₃ has a lower pH than KOH.</em>

4. Synthesis problems. Propose a synthetic route from the starting material to the product. In your answer, show each individual
Troyanec [42]

The reduction of alkyne to an alkene in the first step allows the best reagent to be chosen for each subsequent step.

Describe reagents.

A reagent is merely an essential component of a chemical reaction, it should be mentioned. It is an ingredient that speeds up the reaction.

With H2 and Lindlar's catalyst, an alkyne is reduced to alkene as the initial step in this process. Alkene will then be brominated to produce allyl bromide as the next step.

In this instance, the required allyl alcohol will be produced via the reaction of allyl bromide with NaOH.
