Given below are two statements :

Statement I : In , the carbocation is stabilised by +R effect of –OCH₃ group.

Statement II : In , the carbanion is stabilised by –R effect of –NO₂ group.

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

The compound (X) on

(i) on heating in the presence of anhydrous AlCl₃ and HCl gas gives 2,4-dimethyl pentane

(ii) aromatization gives toluene and

(iii) cyclisation gives methyl cyclohexane

The correct name of compound (X) is:

Correct statements regarding alkyl halides (R–X) among the following are :

A. Alcohol being less polar solvent as compared to water, alcoholic KOH favours elimination reaction with R–X.

B. Order of reactivity towards S_N1 mechanism is C₆H₅–CH₂–Cl > C₆H₅–CHCl–C₆H₅.

C. Non substituted aryl halides exhibit properties similar to alkyl halides.

D. Vinyl chloride is an example of haloalkene and allyl chloride is an example of haloalkyne.

E. R–Cl can be prepared by reacting R–OH with SOCl₂ but Ar–Cl cannot be prepared by reacting Ar–OH with SOCl₂.

Choose the correct answer from the options given below :

An organic compound “x” where molar ratio of C, O and H are equal, on treatment with 50% KOH under reflux followed by acidification produced “y”. The most likely structure of “y” is:

[Molar mass of ‘x’ is 58 g mol⁻¹]
