Identify the product $(A)$ of the following reaction:
$C_2H_5-O-C_2H_5 + CO \xrightarrow[500 \text{ atm}]{BF_3 / 150^{\circ}C} A$

In the following reaction,
${C_2H_5}O{C_2H_5} + 4[H] \xrightarrow{HI} 2X + {H_2}O$
What is $X$ in this reaction?

What product is formed when anisole reacts with concentrated $HNO_3$ and concentrated $H_2SO_4$?

Assertion: Ethyl phenyl ether on reaction with $HBr$ forms phenol and ethyl bromide.
Reason: Cleavage of $C-O$ bond takes place at the ethyl-oxygen bond due to the more stable phenyl-oxygen bond.

Give the common and $\text{IUPAC}$ names for the following ether compound:
$1,1-\text{dimethyl}-2-\text{ethoxycyclohexane}$ (structure shown in image).

Which among the following compounds is obtained as a major product $X$ in the reaction given below?
Anisole $\xrightarrow[AlCl_3 \text{ (anhydrous)}]{acetyl chloride} X$
