A = Diethyl ether B = Ethyl alcohol

C = Carbon tetrachloride D = Water

2) The four liquids probably be

A = Carbon tetrachloride B = Diethyl ether

C = Ethyl alcohol D = Water

3) the four liquids probably be

A = Diethyl ether B = Carbon tetrachloride

C = Ethyl alcohol D = Water

4) The four liquids probably be

C = Diethyl ether D = Water​

Answer 1

Hello there,

The answer for the above question is option 3

Explanation:

As we know, when VP decreases, Boiling Point increases. From the graph, the VP order is:

A>B>C>D

So, order of B.P. will be:

D>C>B>A

In the NCERT, there is a table (Pg 53) which says about the boiling point values of a few compounds. From there, we can form an order of boiling point

I have attached a photo showing the order.

I hope this helps you. Please Mark BRAINLIEST if you find it helpful.✌
