Question

define borderline acid and base with examples in chemistry
​

Answer 1

Answer:

Bases in which the donor atom is N or Cl fall in this category. Thus NH3, Cl-, RCl, and pyridine are borderline bases.

Boader line acid tend to have lower charge and somewhat larger size than hard acids, and higher charge and somewhat smaller size than soft acids. The 2+ ions of the d block, such as Fe2+, Cu2+, Ni2+, and Zn2+, are borderline acids.

Explanation:

Answer 2

Borderline acids are intermediate between hard and soft acids.

Examples: The 2+ ions of the d block, such as Fe2+, Cu2+, Ni2+, and Zn2+

Borderline bases are intermediate between hard and soft bases. They tend to be larger and less electronegative than hard bases, smaller and more electronegative than soft bases.

Examples: Bases in which the donor atom is N or Cl fall in this category. Thus NH3 Cl-, RCl, and pyridine

There are some numbers in examples. They are in subscript.
