Which order for basic character of amine is correct for following compounds? <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/c-8dsyptzy0z3o.png" /> (A) 3>1>2>5>4 (B) 3>2>1>5>4 (C) 3>1>2>4>5 (D) 3>2>1>4>5

Tardigrade Admin · Accepted Answer

Electron releasing group increases basic character of amine and aromatic amine is less basic than aliphatic amine

Basic order

\propto + I

or

+ M

effect

\propto \frac{1}{- I}

or

- \frac{1}{M}

effect

Aliphatic amine is more basic than aromatic amine

Solution

Q. Which order for basic character of amine is correct for following compounds?

$3 > 1 > 2 > 5 > 4$

$3 > 2 > 1 > 5 > 4$

$3 > 1 > 2 > 4 > 5$

$3 > 2 > 1 > 4 > 5$

Electron releasing group increases basic character of amine and aromatic amine is less basic than aliphatic amine

Basic order $\propto + I$ or $+ M$ effect $\propto \frac{1}{- I}$ or $- \frac{1}{M}$ effect

Aliphatic amine is more basic than aromatic amine

Q. Which order for basic character of amine is correct for following compounds?

3>1>2>5>4

3>2>1>5>4

3>1>2>4>5

3>2>1>4>5

Electron releasing group increases basic character of amine and aromatic amine is less basic than aliphatic amine Basic order ∝+I or +M effect ∝−I1​ or −M1​ effect Aliphatic amine is more basic than aromatic amine

$3 > 1 > 2 > 5 > 4$

$3 > 2 > 1 > 5 > 4$

$3 > 1 > 2 > 4 > 5$

$3 > 2 > 1 > 4 > 5$
