Question

swyk: bonding and molecular properti
which of the following compounds would you assume have a low melting point and is volatile?
$agno_3$
$cabr_2$
$ccl_4$
$nacl$

Explanation:

To determine which compound has a low melting point and is volatile, we analyze the type of bonding:

• Ionic compounds (like \(AgNO_3\), \(CaBr_2\), \(NaCl\)) have strong ionic bonds, resulting in high melting points and low volatility.
• Molecular compounds (like \(CCl_4\)) have weaker intermolecular forces (London dispersion forces here), leading to low melting points and higher volatility.

Answer:

C. \(CCl_4\)
