Trimethylamine is less basic than dimethylamine.

Text Solution

AI Generated Solution

To understand why trimethylamine is less basic than dimethylamine, we can break down the explanation into a series of logical steps: ### Step 1: Understand the Structures - **Trimethylamine (N(CH3)3)** has three methyl groups attached to a nitrogen atom. - **Dimethylamine (N(CH3)2H)** has two methyl groups and one hydrogen atom attached to the nitrogen atom. ### Step 2: Analyze Electron Density - Methyl groups (CH3) are electron-donating groups. They increase the electron density on the nitrogen atom, making it more basic. ...

Pyridine is less basic than triethylamine because :

A: Phthalimide is less basic than acetamide. R: Acetamide is more basic than ethyl amine.

Which is less basic than benzyl carbanion ?

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 :

Assertion : Acetanilide is less basic than aniline . Reason : Acetanilide is formed by reaction of aniline with acetic anhydride .
