Design a synthesis of acetophenone from benzene or toluene. 1275q Part 1 out of 5 Choose the best option for the nucleophile pre
Trava [24]

Answer:

A Fridiel craft catalyst will convert benzene to acetophenone.

Permanganate catalyst can be used to convert toluene to acetophenone.

Explanation:

Benzene can be reduced to acetophenone by the addition of anhydrous aluminium chloride, AlCl₃

The mechanism is as follows:

Benzene + Acetyl choloride → acetophenone

To convert toluene to acetophenone, the following steps are necessary:

  • Oxidation of Toluene to Benzoic acid.

     This is done by refluxing toluene with alkaline potassium permanganate         (KMnO₄+ Na₂CO₃).

  • Benzoic acid is converted to Benzoyl chloride by treating with thioyl chloride and heating at about 80 ⁰C.
  • Benzoyl chloride is treated with methyl lithium to form Acetophenone.

"A bicycle's brakes apply 299 N of frictional force to the wheels as the bike moves 24 m
Usimov [2.4K]

Answer:

0.62 N

Explanation:

first of all: 3.0 s = 0.05 m

Let ? be the work that brakes do at 3.0s

24 m ----> 299 N

0.05 m ---->?

? = (0.05 m x 299 N)/ 24

? = (14.95)/ 24

? = 0.622 N

Which lava composition causes the most volcanic eruptions? Why?
ddd [48]

Answer:

Explosive eruptions are favored by high gas content & high viscosity magmas (andesitic to rhyolitic magmas). The explosive bursting of bubbles fragments the magma into clots of liquid that cool as they fall through the air. These solid particles become pyroclasts or volcanic ash.
