A candle’s wick is the fabric string that holds the flame, and it burns down at a constant slow pace when the candle is lit. The wick is usually surrounded by wax.

Question

Which is the most important property of covalent compounds that makes them useful for making candle wax?

a low boiling point
a low melting point
a high boiling point
a high melting point

Answer 1

The most important property of covalent compounds that makes them useful for making candle wax is a low melting point.

Candle wax needs to be able to melt easily when heated, allowing it to flow and fill the mold during production, as well as to melt when the candle is lit to provide a soft, manageable liquid for the wick to draw from. Thus, a low melting point is essential for a functional candle wax.
