Question

vii)
a) BaCl2
is Lewis acid.
b) KC
c) BeCl2
d) Lici​

Answer 1

Answer:

Becl2acid, KCL is lewis acid

Explanation:

*lewis acid can accept a pair of electron. And that's why BeCl2 can accept two or more electrons to compete is octet structure. That's why BeCl2 is considered as a Lewis acid but it is extremely weak Lewis acid.

*BaCl2, barium chloride is not a Lewis acid because barium loses two electrons while chlorine gains one electron thus forming chloride ion. Since both the species have complete octets, it is not a Lewis acid.
