What class of organic product results when 1-heptyne is treated with a mixture of mercuric acetate (HgSO4) in aqueous sulfuric a
Alekssandra [29.7K]

Answer:

<u>heptan-2-one</u>

Explanation:

In this case, the final product would be a ketone: <u>heptan-2-one</u>. To understand why this molecule is produced we have to check the<u> reaction mechanism</u>.

The first step is the <u>protonation</u> of the triple bond to produce the more stable carbocation (a secondary one) by the action of sulfuric acid H_2SO_4. The next step is the <u>attack of water</u> to the carbocation to produce a new bond between C and the O, producing a positive charge in the oxygen. Then, a <u>deprotonation</u> step takes place to produce an <u>enol</u>. Finally, we will have a rearrangement (<u>keto-enol tautomerism</u>) to produce the final ketone.

See figure 1

I hope it helps!

A gas has a volume of 62.65L at O degrees Celsius and 1 atm. At what temperature in Celsius would the volume of the gas be 78.31
Anastaziya [24]

Answer:

The volume of the gas will be 78.31 L at 1.7 °C.

Explanation:

We can find the temperature of the gas by the ideal gas law equation:

PV = nRT

Where:

n: is the number of moles

V: is the volume

T: is the temperature

R: is the gas constant = 0.082 L*atm/(K*mol)

From the initial we can find the number of moles:

n = \frac{P_{1}V_{1}}{RT_{1}} = \frac{1 atm*62.65 L}{(0.082 L*atm/K*mol)*(0 + 273)K} = 2.80 moles

Now, we can find the temperature with the final conditions:

T_{2} = \frac{P_{2}V_{2}}{nR} = \frac{612.0 mmHg*\frac{1 atm}{760 mmHg}*78.31 L}{2.80 moles*0.082 L*atm/(K*mol)} = 274.7 K

The temperature in Celsius is:

T_{2} = 274.7 - 273 = 1.7 ^{\circ} C

Therefore, the volume of the gas will be 78.31 L at 1.7 °C.

I hope it helps you!
