តើចម្លើយមួយណាត្រឹមត្រូវនឹងការតម្រៀបតាមលំដាប់លំដោយ នៃលក្ខណៈបាសរបស់សមាសធាតុខាងក្រោមដោយពឹងផ្អែកលើលំដាប់ថយចុះនៃតម្លៃថេរអុីយ៉ុងកម្មនៃបាសរបស់សមាសធាតុទាំងនោះ ? Which is the correct arrangement of compounds based on decreasing order of Kb value
អាម៉ូញ៉ាក់ < ផេនីលឡាមីន < មេទីលឡាមីន Ammonia < phenyl amine < methyl amine
មេទីលឡាមីន > អាម៉ូញ៉ាក់ >ផេនីលឡាមីន methyl amine > ammonia > phenyl amine
ផេនីលឡាមីន < អាម៉ូញ៉ាក់ < មេទីលឡាមីន Phenyl amine < ammonia < methyl amine
Answer explanation
កាលណា Kb កាន់តែធំ => លក្ខណៈបាសកាន់តែខ្លាំង
