The increasing basicity order of the following compounds is:

Question

Aicharya · Accepted Answer

In case of polar protic solvents, two factors decide the basic character. The positive inductive effect from alkyl groups which increases basicity.

3^{o} > 2^{o} > 1^{o}

Amine

& the Steric Hindrance.

1^{o} > 2^{} > 3^{o}

Thus, the resultant basic character is determined by taking the above two factors into account.

So order will be

2^{o} > 1^{o} > 3^{o}

if methyl group is present as alkyl group otherwise order will be

2 ° > 3 ° > 1 °

.

In aromatic & Aliphatic: Aliphatic Amine are more basic than aromatic because the lone pair of

N

is involved in delocalization.

So basic character is in the order

2^{o} > 1^{o} > 3^{o} > A r o m a t i c A m i n e

So (B) > (A) > (C) > (D)
