Question

please help me with this friends​

Answer 1

Answer:

1. 4) 34°C

As ethanol have hydrogen bonding, it have higher boiling point than diethyl ether

2. 4) POCl3

C2H5-O-C2H5 + PCl5 --- 2C2H5Cl + POCl3

3. 1) C2H5OC2H5

As ether forms peroxy compound due to -O- group

hope this will help you

Answer 2

Answer:

Sure Here is your answer

Explanation:

1.) ANSWER: 34°C

REASON: Here molecular weight of diethyl ether is more than ethanol, hence we would think that Diethyl ether would have more boiling point than that off ethanol. That is wrong, because Ethanol has Intermolecular Hydrogen Bonding , where are diethyl ether doesn't. So basically compounds with Intermolecular H. bonds will have more M.P & B.P than molecules without any Hydrogen bonding. So from the options we can clearly see that all the options are above the B.P of Ethanol (i.e) 78°C except 4th option, hence it is our required answer.

2.) C₂H₅ ─ O ─ C₂H₅ + PCl₅ → C₂H₅Cl + X

ANSWER: Here X is POCl₃ (Phosphorous Oxy Chloride)

REASON:  Refer the given attachment

3.) ANSWER: C₂H₅ ─ O ─ C₂H₅

   REASON: Ether forms peroxy linkage always because of presence of

-O-  linkage group between them. Mechanism is given below
