The major product in Reimer-Tiemann reaction is $X$. The reactants are $Y$ and $Z, X, Y$ and $Z$ are respectively

The increasing order of boiling points of the following is

$$ \begin{array}{cccc} \mathrm{CH}_3-\mathrm{O}-\mathrm{CH}_3 & \mathrm{CH}_3 \mathrm{CHO} & \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_3 & \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH} \\ \text { I } & \text { II } & \text { III } & \text { IV } \end{array} $$

What is the value of ' $n$ ' in ' $Z$ ' of the following sequence?

Lauryl alcohol $\xrightarrow{\mathrm{H}_{2} \mathrm{SO}_{4}}$

( $X$ )

Lauryl hydrogen sulphate $\xrightarrow{\mathrm{NaOH}(a q)}$

( $Y$ )

$ \mathrm{CH}_{3}-\left(\mathrm{CH}_{2}\right)_{n}-\mathrm{CH}_{2} \mathrm{OSO}_{3} \mathrm{Na} $

(Z)

Sodium lauryl sulphate

Match the following

The correct answer is
