Mixed aldol condensations involving benzaldehyde yield typically a single product. draw the structure of the partner that was us
1 answer:
The partner that is used along with benzaldehyde is acetophenone to yield 1,3-Diphenylprop-2-en-1-one.
<h3>What is Adol Condensation?</h3>In adol condensation, aldehydes or ketones having α - H atoms undergo condensation in the presence of a dilute alkali to form β - hydroxy aldehydes or ketones.
<h3>What is Mixed Adol Condensation?</h3>Under mixed or crossed adol condensation,
- two different aldehyde molecules or
- 2 different ketone molecules or
- one aldehyde and one ketone molecule
undergoes condensation in the presence of dilute alkali to form a mixture of β - hydroxy aldehyde or ketone.
The following reaction takes place:

<u>Answer:</u> The final temperature of the mixture is 49°C
<u>Explanation:</u>
To calculate the mass of water, we use the equation:
- <u>For cold water:</u>
Density of cold water = 1 g/mL
Volume of cold water = 230.0 mL
Putting values in above equation, we get:
- <u>For hot water:</u>
Density of hot water = 1 g/mL
Volume of hot water = 120.0 mL
Putting values in above equation, we get:
When hot water is mixed with cold water, the amount of heat released by hot water will be equal to the amount of heat absorbed by cold water.
The equation used to calculate heat released or absorbed follows:
......(1)
where,
q = heat absorbed or released
= mass of hot water = 120 g
= mass of cold water = 230 g
= final temperature = ?°C
= initial temperature of hot water = 95°C
= initial temperature of cold water = 25°C
c = specific heat of water = 4.186 J/g°C
Putting values in equation 1, we get:
Hence, the final temperature of the mixture is 49°C
