ahrayia [7]

Answer:

See below.

Step-by-step explanation:

Ethers react with HI at high temperature to produce an alky halide and an alcohol.

R-OR' + HI ⟶ R-I + H-OR'

Benzylic ethers react by an Sₙ1 mechanism by forming the stable benzyl cation.

PhCH₂-OR + HI ⟶ PhCH₂-O⁺(H)R + I⁻ Protonation of the ether
PhCH₂-O⁺(H)R ⟶ PhCH₂⁺ + HOR Sₙ1 ionization of oxonium ion
PhCH₂⁺ + I⁻ ⟶ PhCH₂-I Nucleophilic attack by I⁻

If there is excess HI, the alcohol formed in Step 2 is also converted to an alkyl iodide:

ROH +HI ⟶ R-I + H-OH

Thus, benzyl ethyl ether reacts to form benzyl iodide (a) and ethanol (b).

The ethanol reacts with excess HI in an Sₙ2 reaction to form ethyl iodide (c).

After adding 20.0 mL of 5% NaOH solution into the remaining organic layer, followed by mixing and venting, the solution separate

Arisa [49]

Answer:

Explanation:

The objective of this experiment is to match the expected result with each of the propositions given after the experiment had been carried out.

1. The top layer was the organic  layer. This is because all the organic compounds have lesser density than water except chloroform that will be formed when NaOH is added.

2. 9-fluorenone was most soluble in the organic layer. This is so as a result of its non-polar carbon structure.

3. Deprotonated chloroanilic acid was most soluble in the aqueous layer as a result of the formation of an electrovalent bond with water.

4. The bottom layer was the aqueous layer as a result of the huge amount of water density.

5. The organic layer was a yellow colored solution.

6. The aqueous layer turned into a pink colored solution.

Provide the name(s) for the constitutional isomer(s) with the molecular formula C7H16 that have an unbranched chain. If there is

Tema [17]

Answer:

Explanation:

Isomerism is the occurrence of two or more compounds with the same molecular formula but different structures. Isomers with the same molecular formula and belonging to the same homologous series tends to have similar chemical properties but slightly different physical properties as a result of their constitutional (structural differences).

Thus,as the number of carbon atoms in a molecule increases , the number of isomer also increases. In the given question C7H16 is known as heptane which have nine (9) possible constitutional (structural) isomers.

The main objective is to provide the names for the constitutional isomers with the molecular formula C7H16.

In the attached file below; we've shown the possible isomers of heptane (C7H16). and we've identify them by naming them.
