Q. According to hard and soft acid-base principle, a hard acid
A) Has low charge density
B) Shows preference for soft bases
C) Shows preference for donor atoms of low electronegativity
D) Is not polarisable
Explanation
(d)
A hard acid has high charge density, shows preference for hard bases $i.e$., for atoms of high electronegativity. Moreover, its outer electrons are not easily distorted $i.e$., it is non-polaris able.
