A student is given one compound among the following compounds that gives positive test with Tollen's reagent.

The compound is:

‘\( x \)’ is the product which is obtained from benzene by reacting it with carbon monoxide and hydrogen chloride in the presence of cuprous chloride. ‘\( y \)’ is the major product obtained from the benzene by reacting it with ethanoyl chloride in the presence of anhydrous \( \mathrm{AlCl_3} \). Product (major) obtained by heating \( x \) and \( y \) in the presence of alkali is \( z \). Total number of \( \pi \)(pi) electrons in \( z \) is ______.

Given below are two statements:

Statement (I): Benzyl chloride reacts faster in \( \mathrm{S_{N}1} \) mechanism than ethyl chloride.

Statement (II): Ethyl carbocation intermediate is less stabilized by hyperconjugation than benzyl carbocation by resonance.

In the light of the above statements, choose the correct answer from the options given below:

n-Butane on monochlorination under photochemical condition gives an optically active compound “P”. “P” on further chlorination gives dichloro compounds.
The number of dichloro compounds obtained (ignore stereoisomers) is:

A hydrocarbon ‘P’ (\( \mathrm{C_4H_8} \)) on reaction with HCl gives an optically active compound ‘Q’ (\( \mathrm{C_4H_9Cl} \)) which on reaction with one mole of ammonia gives compound ‘R’ (\( \mathrm{C_4H_{11}N} \)). ‘R’ on diazotization followed by hydrolysis gives ‘S’. Identify P, Q, R and S.

The following structures are:

A hydroxy compound (\( X \)) with molar mass \( 122 \, \mathrm{g \, mol^{-1}} \) is acetylated with acetic anhydride, using a large excess of the reagent ensuring complete acetylation of all hydroxyl groups. The product obtained has a molar mass of \( 290 \, \mathrm{g \, mol^{-1}} \). The number of hydroxyl groups present in compound (\( X \)) is:
