PAPER 1 (1.) The amine that reacts with Hinsberg's reagent to give an alkali insoluble product is [NEET Odisha 2019] (1) (2) (3) (4) (2.) The correct order of the basic strength of methyl substituted amines in aqueous solution is : (1) ( 3 3 2 3 ) ( ) 2 3 CH NH CH NH CH N   [2019] (2) ( 3 3 2 3 ) ( ) 3 2 CH N CH NH CH NH   (3) ( 3 3 3 2 ) ( ) 3 2 CH N CH NH CH NH   (4) 3 2 3 3 ( ) ( ) 2 3 CH NH CH NH CH N   (3.) Nitration of aniline in strong acidic medium also gives m -nitroaniline because [2018] (1) Inspite of substituents nitro group always goes to only m -position. (2) In electrophilic substitution reactions, amino group is meta directive. (3) In acidic (strong) medium aniline is present asanilinium ion. (4) In absence of substituents, nitro group always goes to m -position. (4.) The correct increasing order of basic strength for the following compounds is : [2017] (I) (II) (III) (1) III  I  II (2) III  II  I (3) II  I  III (4) II  III  I
(5.) The electrolytic reduction of nitrobenzene in strongly acidic medium produces :- [2015] (1) Azoxybenzene (2) Azobenzene (3) Aniline (4) p -Aminophenol (6.) Method by which aniline cannot be prepared is: [2015 RS] (1) hydrolysis ofphenylisocyanide with acidic solution (2) degradation of benzamide with bromine in alkaline solution (3) reduction of nitrobenzene with H / Pd 2 in ethanol (4) potassium salt of phthalimide treated with chlorobenzene followed by hydrolysis with aqueous NaOH solution. (7.) In a set of reactions m -bromobenzoic acid gave a product D . Identify the product D . [2011] (1) (2) (3) (4) (8.) Which of the following statements about primary amines is 'False'? [2010] (1) Alkyl amines are stronger bases than aryl amines
(2) Alkyl amines react with nitrous acid to produce alcohols (3) Aryl amines react with nitrous acid to produce phenols (4) Alkyl amines are stronger bases than ammonia (9.) Predict the product: [2009] (1) (2) (3) (4) (10.) The major organic product formed from the following reaction : [2005] is (1) (2) (3) (4)
(11.) The consituent of the powerful explosive RDX is formed during the nitration of [2000] (1) Toluene (2) Phenol (3) Glycerol (4) Urotropine (12.) Aniline is reacted with bromine water and the resulting product is treated with an aqueous solution of sodium nitrite in presence of dilute hydrochloric acid. The compound so formed is converted into a tetrafluoroborate which is subsequently heated dry. The final product is (1) 1,3,5-Tribromobenzene (2) p -Bromofluorobenzene (3) p -Bromoaniline (4) 2,4,6-Tribromofluorobenzene (13.) When aniline reacts with oil of bitter almonds (C H CHO 6 5 ) , condensation takes place and benzal derivative is formed. This is known as [1995] (1) Million's base (2) Schiff's reagent (3) Schiff's base (4) Benedict's reagent (14.) Mark the correct statement [1988] (1) Methylamine is slightly acidic (2) Methylamine is less basic than ammonia (3) Methylamine is a stronger base than ammonia (4) Methylamine forms salts withalkalies. (15.) On hydrolysis of a "compound", two compounds are obtained. One of which on treatment with sodium nitrite and hydrochloric acid gives a product which does not respond to iodoform test. The second one reduces Tollen's reagent and Fehling's solution. The "compound" is [NEET Kar. 2013] (1) 3 2 2 3 ( )2 CH CH CH CON CH (2) CH CH CH NC 3 2 2 (3) CH CH CH CN 3 2 2 (4) CH CH CH ON O 3 2 2 = (16.) Acetamide is treated with the following reagents separately. Which one of these would yield methylamine? [2010] (1) NaOH Br − 2 (2) Sodalime (3) Hot conc. H SO2 4 (4) PCl5 (17.) The final product C , obtained in this reaction would be [2003]
