188. Identify the U in below reaction:
Reason : The lone pair of electrons on the nitrogen atom in aliphatic amines is delocalized over the aromatic ring through resonance.
191. Assertion : Ortho-substituted aniline is less basic than aniline. Reason : Ortho-substituted aniline experiences both electronic effects and steric hindrance, reducing its basicity.
192. Assertion : Electron-releasing groups increase the basic strength of aniline derivatives. Reason : Electron-releasing groups donate electron density to the benzene ring, making the lone pair on nitrogen more available for protonation.
193. Assertion : The basic strength of methylamine is higher than ammonia in aqueous solutions. Reason : Methylamine forms stronger hydrogen bonds with water compared to ammonia.
194. Assertion : Secondary amines have lower boiling points than primary amines of similar molecular mass. Reason : Secondary amines cannot form intermolecular hydrogen bonds.
195. Assertion : Aniline reacts with bromine water to give 2,4,6-tribromoaniline. Reason : Aniline is a strong electron-withdrawing group.
196. Assertion : p-Nitroaniline is less basic than p-methoxyaniline. Reason : The -NO2 group at the para position is an electron-withdrawing group, whereas -OCH3 is an electron-releasing group.
197. Assertion : Tertiary amines are less soluble in water compared to primary amines of similar molecular weight. Reason : Tertiary amines lack hydrogen atoms for hydrogen bonding with water.
198. Assertion : Aniline is less basic than ammonia. Reason : The lone pair of electrons on the nitrogen atom in aniline participates in resonance with the benzene ring, reducing its availability for protonation.
199. Assertion : p-Toluidine is more basic than aniline. Reason : The –CH3 group in p-toluidine donates electron density to the benzene ring, increasing the availability of the lone pair on nitrogen.
200. Assertion : Methylamine has a higher boiling point than dimethylamine. Reason : Methylamine forms stronger hydrogen bonds compared to dimethylamine due to more hydrogen atoms on the nitrogen.
201. Assertion : Benzenediazonium chloride is stable at low temperatures. Reason : At low temperatures, the decomposition of benzenediazonium chloride is kinetically hindered.
202. Assertion : The boiling points of primary amines are higher than those of alcohols of similar molecular weight. Reason : Hydrogen bonding in amines is stronger than in alcohols due to the higher electronegativity of nitrogen compared to oxygen.
203. Assertion : The reaction of nitrous acid with primary aliphatic amines produce alcohols. Reason : Primary aliphatic amines form unstable diazonium salts, which decompose to give alcohols.
204. Assertion : Amines can be distinguished by the Hinsberg test. Reason : Hinsberg’s reagent reacts differently with primary, secondary, and tertiary amines, forming distinguishable products.
