Answer:
B. A tertiary alcohol; a secondary alcohol
Explanation:
Grignard reagent has a formula RMgX where X is a halogen, and R is an alkyl or aryl group.
Grignard reagent reacts with aldehydes and ketones to form alcohol. However the classification (that is; Primary, secondary and tertiary) varies depending on which it reacts with.
2-butanone is a ketone.
Ketones reacts with Grignard reagent to form tertiary alcohol
Butanal is an aldehyde.
Aldeyde reacts with grignard reagent to form Secondary alcohol
The answer is; Tertiary alcohol; Secondary alcohol
Answer:
13.5 %
Explanation:
First we<u> calculate the mass of 500 mL of water</u>, using <em>its density</em>:
- 500 mL * 1.00 g/mL = 500 g
Then we <u>calculate the mass percent of potassium sulfate</u>, using the formula:
Mass of Potassium Sulfate / Total Mass * 100%
- 78 g / (78 + 500) g * 100 % = 13.5 %
