Question

13. एल्काइल ऐमीन अमोनिया से प्रबल क्षार है, क्यो​

Answer 1

Answer:

ऐलिफैटिक ऐमीन, नाइट्रोजन परमाणु पर ऐल्किल समूहों के +I प्रभाव के कारण अधिक इलेक्ट्रॉन घनत्व होने से अमोनिया से प्रबल क्षारक होते हैं। इनके pK, मान 3 से 4.22 के मध्य होते हैं।

Answer 2

English Translation:

Why is alkyl amine a stronger base than ammonia?

The ability of lone pairs on the nitrogen atom to donate electrons is crucial to the formation of amines.

• Due to the presence of an alkyl group, alkylamines (methylamine) are more powerful bases than ammonia.
• In order for the atom to supply more electrons and behave as a base, it donates additional electrons to the atom (+I effect). While there is no such charge in ammonia.
• Alkyl group (R) drives electrons towards nitrogen in alkyl amine due to its electron-releasing nature, which increases the availability of the unshared electron pair for sharing with the proton of the acid.
• Alkyl amine hence has higher basicity than ammonia due to the inclusion of an alkyl group, which tends to increase basicity.
