Diethyl ether and air give ether hydroperoxide. The mechanism of the reaction is

What are $X$ and $Y$ in the following reaction?

One mole of an organic compound $A$ with the formula $C_{3}H_{8}O$ reacts completely with two moles of $HI$ to form $X$ and $Y$. When $Y$ is boiled with aqueous alkali,it forms $Z$. $Z$ answers the iodoform test. The compound $A$ is

An ether $(A)$,$C_5H_{12}O$,when heated with excess of hot concentrated $HI$ produced two alkyl halides which when treated with $NaOH$ yielded compounds $(B)$ and $(C)$. Oxidation of $(B)$ and $(C)$ gave a propanone and an ethanoic acid respectively. The $IUPAC$ name of the ether $(A)$ is

In the reaction,$C_2H_5OC_2H_5 + CO \xrightarrow[150^{\circ}C, 500 \text{ atm pressure}]{BF_3} X$. What is $X$?

The compound formed when ethyl bromide is heated with dry silver oxide is
