Vedclass · Accepted Answer

Both $Cu^{+}$ and $Cu^{2+}$ are stable with $F^{-}$.

Vedclass · Answer

(D) In aqueous solution,$Cu^{2+}$ is more stable than $Cu^{+}$ due to its much more negative hydration enthalpy,which compensates for the second ionization enthalpy of copper.$Cu^{2+}$ has a $3d^9$ configuration (one unpaired electron),making it paramagnetic,while $Cu^{+}$ has a $3d^{10}$ configuration (no unpaired electrons),making it diamagnetic.$Cu^{2+}$ compounds are generally blue due to $d-d$ transitions,while $Cu^{+}$ compounds are colourless due to the filled $d$-subshell.$Cu^{+}$ is unstable in aqueous solution and undergoes disproportionation into $Cu$ and $Cu^{2+}$.Therefore,the statement that both $Cu^{+}$ and $Cu^{2+}$ are stable with $F^{-}$ is incorrect,as $Cu^{+}$ is generally unstable in aqueous environments.

Which of the following statements is not correct about $Cu^{2+}$ and $Cu^{+}$?
