Question:

$\text{The most acidic oxide among the following is -}$

Options:

1. $\text{MgO}$
2. $\text{BeO}$
3. $\text{BaO}$
4. $\text{CaO}$

Solution:

$\text{HINT: Basic strength of oxide } \propto \text{ Metallic character}$ $\text{Explanation:}$ $\text{The basic strength of metal oxide is directly proportional to the metallic character of the element.}$ $\text{On moving down the group, the metallic character of the element increases.}$ $\text{Since the ionization energy decreases going down a group (or increases going up a group), the increased ability for metals lower in a group to lose electrons makes them more reactive.}$ $\text{Due to this basicity of its oxide increases down the group.}$ $\text{Hence, } \text{BeO} \text{ is the most acidic oxide.}$
