Question

Which of the following statements about bonding is correct?

• A. Only van der Waals forces exist between polar molecules
• B. Dipoles are the result of the equal sharing of electrons
• C. $Cu\left(s\right)$ is a network covalent solid
• D. Hydrogen bonds exist between the molecules of $HCl$
• E. $NaCl\left(aq\right)$ has attraction between the molecules and the ions

Answer 1

The correct option is E $NaCl\left(aq\right)$ has attraction between the molecules and the ions

The statement $E$ is correct.
$NaCl\left(aq\right)$ has attraction between the molecules and the ions

In an aqueous solution, $NaCl$ dissociates into $N{a}^{+}$ ions and chloride $C{l}^{-}$ ions.

$NaCl\left(aq\right)\rightleftharpoons N{a}^{+}\left(aq\right)+C{l}^{-}\left(aq\right)$.

These sodium ions and chloride ions are hydrated. That is, each odium ion is surrounded by several water molecules and each chloride ion is also surrounded by several water molecules.

There there are interactions between ions and water molecules.
