Question

Which of the following oxide is expected to react readily with $NaOH$?

• A. $N{a}_{2}O$
• B. $CaO$
• C. $NO$
• D. $C{l}_2{O}_7$

Answer 1

The correct option is D $C{l}_2{O}_7$

Acidic oxide is expected to react readily with $NaOH$.
$N{a}_{2}O$ is metal oxide i.e basic oxide.
$CaO$ also is metal oxide i.e basic oxide.
$NO$ is neutral oxide.
$C{l}_2{O}_7$ is non metallic oxide i.e., acidic oxide.
