Given below are two statements:
Statement I: Dimethyl ether is completely soluble in water. However, diethyl ether is soluble in water to a very small extent.
Statement II: Sodium metal can be used to dry diethyl ether and not ethyl alcohol
In the light of the above statements, choose the correct answer from the options given below.

Which among the following halides will generate the most stable carbocation in the nucleophilic substitution reaction?

Identify the product [A] and [B], respectively in the following reaction:

An organic compound \( (X) \) with molecular formula \( \mathrm{C_3H_6O} \) is not readily oxidized. On reduction it gives \( \mathrm{C_3H_8O} \) \( (Y) \) which reacts with \( \mathrm{HBr} \) to give a bromide \( (Z) \) which is converted to Grignard reagent. This Grignard reagent on reaction with \( (X) \) followed by hydrolysis give \( 2, 3 \)-dimethylbutan-\( 2 \)-ol. Compounds \( (X) \), \( (Y) \) and \( (Z) \) respectively are:

A toxic compound ‘A’ when reacted with \( \mathrm{NaCN} \) in aqueous acidic medium yields an edible cooking component and food preservative ‘'B’'. '‘B’' is converted to '‘C’' by diborane and can be used as an additive to petrol to reduce emission. ‘'C’' upon reaction with oleum at \( 140^\circ \mathrm{C} \) yields an inhalable anesthetic '‘D’'. Identify ‘'A'’, '‘B’', '‘C'’ & '‘D’', respectively:

The incorrect statement among the following is:

Which one of the following reactions will not lead to the desired ether formation in major proportion? (iso-Bu \( \Rightarrow \) isobutyl, sec-Bu \( \Rightarrow \) sec-butyl, nPr \( \Rightarrow \) n-propyl, t-Bu \( \Rightarrow \) tert-butyl, Et \( \Rightarrow \) ethyl)

Given below are two statements:
Statements (I): The boiling points of alcohols and phenols increase with increase in the number of C-atoms.
Statement (II): The boiling points of alcohols and phenols are higher in comparison to other class of compounds such as ethers, haloalkanes.
In the light of the above statements, choose the correct answer from the options given below:

The product B formed in the following reaction sequence is:

Which one of the following, with \( \mathrm{HBr} \) will give a phenol?
