Multiple Choice

AB is predominantly ionic as $$\displaystyle A^{+}B^{-}$$ if___________.

A$$\displaystyle \left ( IP \right )_{A}< \left ( IP \right )_{B}$$
Correct Answer
B$$\displaystyle \left ( EA \right )_{A}< \left ( EA \right )_{B}$$
Correct Answer
C$$\displaystyle \left ( EN \right )_{A}< \left ( EN \right )_{B}$$
Correct Answer
DSize of $$\displaystyle A< $$ size of B

Solution

A molecule AB will be predominately ionic if the ionization potentil electron affinity and electronegativity of cation are smaller than those of anion. Due to this, the bond pair of electrons are less strongly attracted by the cation and are more towards anion.
