Nitrobenzene is indeed toxic and readily absorbed dermally. It is the primary industrial precursor for aniline via reduction. Additionally, its oily nature and scent have historically led to its use in various polishes and dyes, confirming all three statements are correct.

The reaction of benzene with chlorine in the presence of a Lewis acid catalyst like iron (or FeCl3) is a classic electrophilic aromatic substitution reaction. The iron catalyst facilitates the formation of the chloronium ion, which substitutes a hydrogen atom on the benzene ring to produce chlorobenzene and hydrogen chloride gas.

Benzene's stable ring structure resists addition reactions due to its aromaticity. While it can undergo substitution, oxidation, and some special types of addition reactions, it generally does not readily polymerize.

In this reaction, bromine adds to the benzene ring, resulting in the formation of a new compound. This is an example of an electrophilic addition reaction, where the bromine molecule is electrophilic and attacks the π electrons of the benzene ring.

Concentrated nitric acid nitrates the sucrose molecule, resulting in the formation of nitrosucrose. This reaction involves the substitution of hydroxyl groups with nitro groups.

Among the given options, Toluene is the compound that will be sulfonated easily. Toluene is an aromatic hydrocarbon with a benzene ring substituted by a methyl group (CH3) at the para position. Sulfonation involves the substitution of a hydroxyl group (-OH) with a sulfonic acid group (-SO3H) on the aromatic ring. The electron-donating methyl group in Toluene stabilizes the positive charge that forms during the sulfonation process, making it easier for the sulfonation reaction to occur compared to the other options.

When benzene (C6H6) is heated with hydrogen gas (H2) in the presence of platinum as a catalyst, three moles of hydrogen gas are formed through a series of reactions. Specifically, benzene undergoes electrophilic substitution reactions, specifically substitution of hydrogen atoms by hydrogen gas molecules. This results in the formation of three hydrogen molecules for each benzene molecule.

Chlorobenzene reacting with NaOH at 360°C and 150 atm is a nucleophilic substitution reaction that produces phenol, not benzene. The other options are methods that can produce benzene through decarboxylation, reduction, or hydrolysis reactions.
