G propose a different reaction or method for the reduction of 9-fluorenone and show the mechanism
Answers
There are several methods that can be used for the reduction of 9-fluorenone. One of the most common methods is the use of sodium borohydride (NaBH4) as a reducing agent.
The reaction mechanism for this method is as follows:
Step 1: The NaBH4 molecule donates a hydride ion (H-) to the carbonyl group of 9-fluorenone, forming an alkoxide intermediate.
Step 2: The alkoxide intermediate is then protonated by a proton source (such as water or an acid) to form the corresponding alcohol.
The overall reaction can be represented as:
9-fluorenone + NaBH4 + H2O → 9-fluorenol + Na+ + BH3OH-
Another method that can be used for the reduction of 9-fluorenone is the use of lithium aluminum hydride (LiAlH4) as a reducing agent. The reaction mechanism for this method is similar to that of the NaBH4 reduction, with the LiAlH4 molecule donating a hydride ion to the carbonyl group of 9-fluorenone and the resulting alkoxide intermediate being protonated to form the corresponding alcohol. The overall reaction can be represented as:
9-fluorenone + LiAlH4 + H2O → 9-fluorenol + Li+ + AlH3OH-
Both of these methods are effective for the reduction of 9-fluorenone, and the choice of which method to use will depend on the specific conditions and requirements of the reaction.

Answer : The amount of heat needed are, 8464.5 J
Explanation :
Formula used :
where,
q = heat gained = ?
m = mass of water = 45.0 g
c = specific heat of water =
= final temperature =
= initial temperature =
Now put all the given values in the above formula, we get:
Thus, the amount of heat needed are, 8464.5 J
m is the mass of the water, Cp is the specific heat of water and ∆T is the change in temperature of the water (final-initial temperature). q is the energy involved in the reaction, measured in joules.
q=(45.0) x (4.184 Jg^-1/°C^-1) x (45°C)
q=8472.6 Joules

D. It depends on the amount of substance present.
Answers
An intensive property of matter is independent of the amount of substance present and is inherent to the material itself. Thus, the correct statement is 'It is the same for every sample of a single substance.' Examples of intensive properties include temperature, density, and color.
An intensive property of matter is a characteristic that does not change based on the amount of a substance. It is independent of the quantity of the substance present and is inherent to the material itself. Therefore, the statement which best describes an intensive property of matter would be 'It is the same for every sample of a single substance.'
Examples of intensive properties include temperature, density, and color. For instance, if you divide a gold bar in half, each half will have the same density and color as the original bar, because these properties are independent of the amount of substance present.
