Arrange the following substances in the increasing order of their normal boiling points: Ether,Carbon tetrachloride,Ethanol,and Water.

Find the missing reagents $(x)$ and $(y)$ for the following reaction sequence:

Given below are two statements:
Statement $(I)$: The boiling points of alcohols and phenols increase with an increase in the number of $C$ atoms.
Statement $(II)$: The boiling points of alcohols and phenols are higher in comparison to other classes of compounds such as ethers and haloalkanes.
In the light of the above statements,choose the correct answer from the options given below:

Which among the following compounds has the lowest boiling point?

Product $(P)$ is
