Answer:
47.36mL
Explanation:
Using Boyles law equation, which states that:
P1V1 = P2V2
Where;
V1 = initial volume (mL)
V2 = final volume (mL)
P1 = initial pressure (atm)
P2 = final pressure (atm)
Based on the provided information, V1 = 25.3mL, P1 = 152 kPa, V2 = ?, P2 = 0.804atm
First, we need to convert 152kPa to atm by dividing by 101
1kPa = 0.0099atm
152kPa = 1.505atm
P1V1 = P2V2
1.505 × 25.3 = 0.804 × V2
38.08 = 0.804V2
V2 = 38.08/0.804
V2 = 47.36mL
1 mole ----------------- 6.02 x 10²³ molecules
10.0 moles ----------- ( molecules C2H6O)
molecules = 10.0 x ( 6.02 x 10²³ ) / 1
molecules = 6.02 x 10²⁴ / 1
= <span> 6.02 x 10²⁴ molecules of C2H6O
</span>
Answer:
The product of the reaction between a ketone and an alcohol is initially a hemiketal which yields a ketal on further reaction with another alcohol molecule.
The structure is found in the attachment.
Explanation:
This reaction is a <em>nucleophilic addition to the carbonyl group</em>. In organic chemistry, <em>a nucleophilic addition reaction is an addition reaction where a chemical compound with an electron-deficient or </em><em>electrophilic</em><em> double or triple bond, a pi (π) bond, reacts with electron-rich reactant, termed a </em><em>nucleophile</em><em>, with the elimination of the double bond and creation of two new single, or sigma (σ), bonds.</em>
In the reaction between a ketone and an alcohol, the <em>carbonyl</em> group of the ketone serves as the <em>electrophile</em> while the <em>hydroxyl</em> group of the alcohol is the <em>nucleophile</em>. The first product is known as a hemiketal because a single alcohol group has been aded to the carbonyl group of the ketone. Further nucleophilic additon of an alcohol group initiated by the presence of an acid e.g hydrochloric acid, results in the formation of a ketal which has two alcohol group added to the original ketone.
Aluminium fluoride is the name of the ionic compound
