Question

compare nacl from wax/candle
which of the following best describes the difference between
the bonding and properties of sodium chloride (nacl) and
wax?
a. nacl forms through the sharing of electrons and has low
melting and boiling points, while wax forms through electron
transfer and has high melting and boiling points.
b. nacl forms through electron transfer and tends to be a solid
with high melting and boiling points, while wax forms through
electron sharing and is typically a solid at room temperature with
low melting and boiling points.
c. both nacl and wax form through electron sharing and have
similar melting and boiling points.
d. nacl forms through sharing of protons, while wax forms
through electron transfer.

Explanation:

• Sodium chloride (\(NaCl\)) is an ionic compound. Ionic compounds form through electron transfer (sodium donates an electron to chlorine). Ionic compounds generally have high melting and boiling points because of the strong electrostatic forces between ions.
• Wax is a covalent compound (usually made of long - chain hydrocarbons). Covalent compounds form through electron sharing. Covalent compounds (especially non - polar ones like hydrocarbons in wax) typically have low melting and boiling points as the intermolecular forces (van der Waals forces) are relatively weak.

Answer:

B. NaCl forms through electron transfer and tends to be a solid with high melting and boiling points, while wax forms through electron sharing and is typically a solid at room temperature with low melting and boiling points.
