Answer:
in a conical flask. Describe how the volume of sodium hydroxide solution needed to react completely with the weak acids in 25cm cubed of this champagne can be found by titration, using phenolphthalein indicator.
Addition of water to an alkyne gives a keto‑enol tautomer product and that is the product changed into 2-pentanone, then the alkyne need to had been 1-pentyne. 2-pentyne might have given a combination of 2- and 3-pentanone.
<h3>
What is the keto-enol means in tautomer?</h3>
They carries a carbonyl bond even as enol implies the presence of a double bond and a hydroxyl group. The keto-enol tautomerization equilibrium is depending on stabilization elements of each the keto tautomer and the enol tautomer.
- The enol that could provide 2-pentanone might had been pent-1- en - 2 -ol. Because an equilibrium favors the ketone so greatly, equilibrium isn't an excellent description.
- If the ketone have been handled with bromine, little response might be visible because the enol content material might be too low.
- If a catalyst have been delivered, NaOH for example, then formation of the enolate of pent-1-en - 2 - ol might shape and react with bromine.
- This might finally provide a bromoform product. Under acidic conditions, the enol might desire formation of the greater substituted enol constant with alkene stability.
The answer is C, Sugar.
An array of chemical reactions done by plants to transform energy from the Sun into chemical energy, that is, in the form of sugar is known as photosynthesis. Primarily, the plants utilize sunlight's energy to react water and carbon dioxide to generate glucose (sugar) and oxygen. In plants, the process of photosynthesis takes place in the chloroplasts.
