An amine on treatment with ` HNO_2` evolved `N_2` The amine on exhaustive methylation with ` CH_3 I` formed a quatermary dalt containing ` 59.07%` iodine . The amine is likely to be:

A

`CH_3NH_2`

B

`(CH_3)_2NH`

C

`C_2H_5NH_2`

D

`(CH_3)_3N`

Text Solution

Verified by Experts

The correct Answer is:
C
Evolution of `N_2` with `HNO_2` suggests that `1^2` amine [either (a) or (c ) ].
` 59. 07 gm` if (I) is present in ` 100 gm` of compound ` 127 gm` of (I) ( 1 mol) in present in `(100 xx 127)/( 59. 07) = 215`

Amides on treatment with Br_2 and KOH form the amines having the underline(" same number of carbon atoms").

Assertion : When acetamide reacts with NaOH and Br_(2) , methyl amine is formed. Reason : The reaction occurs through intermediate formation of isocyanate.

A compound (X) has the molecular formula C_3 H_7 NO . With Br_2 and KOH , (X) gives (Y) . (Y) responds to mustard oil reaction . (Y) upon treatment with HNO_2 evolves N_2 and gives an alcohol (Z) which gives iodoform test , (X) is likelty to be :

When acetamide is treated with Br_2 and an alkali, a primary amine containing one carbon atom less than the starting amide is formed. Name the reaction and write the balanced equation.

A primary amine, RNH_(2) can be reacted with CH_(3)-X to get secondary amine, R-NHCH(3) , but the only disadvantage is that 3^(@) amine and quaternary ammonium salts are also obtained as side products. Can your suggest a method where RNH_(2) forms only 2^(@) amine?

Nitrosoamines (R_2 N-N=O) are insoluble in water. On heating them with conc. H_2 SO_4 , they give sec. amines. The reaction is called

The lone pair of amines makes them basic. They react with acids to form acid-base salts. Amines are more basic than alcohols, ethers and water. When an amine is dissolved in water, an equilibrium is established , where water acts as an acid and transfer a proton to the amine. The basic strength of an amine can be measured by basicity constant K_(b) . Arylamines are less basic than alkylamines because the lone pair of nitrogen is delocalised with the aromatic ring and are less available for donation. Substituted arylamines can be either more basic or less basic than aniline , depending on the substituted . ERG substituents, such as -CH_(3), -NH_(2) and -OCH_(3) increases the basicity and EWG substituents , such as -Cl, -NO_(2) and -CN decreases basicity. While sp^(2)- hybridized nitrogen atom in pyridine is less basic then the sp^(3) -hybridized nitrogen in an alkylamine. The most basic carbanion is :
