Question

a key ch 201 synthesis is the production of 1,2-diphenyl-ethyne (diphenylacetylene) from 1,2-dibromo-1,2-diphenyl-ethane (meso-stilbene dibromide). assume the synthesis begins with 20.0 g of the substituted ethane. upon completion of the reaction, a ch 201 student recrystallizes their product, diphenylacetylene, in hot methanol. the student began the recrystallization with 9.54 g of product. recrystallization yielded 5.78 g. what is their percent recovery?47.760.628.923.415.9

Answer 1

The percent recovery of the recrystallized product is 60.6%.

Therefore, the correct answer is: option '60.6'.

Step-by-step explanation:

First, we need to calculate the percent recovery.

The initial amount of product used in the recrystallization is 9.54 g, and the final yield is 5.78 g.

We can use the formula:

Percent Recovery = (Final Yield / Initial Amount) * 100%

Plugging in the values, we get:

Percent Recovery = (5.78 g / 9.54 g) * 100%

= 60.6%

Therefore, the percent recovery of the recrystallized product is 60.6%.
