Which unsaturated aliphatic hydrocarbon composed of 20 carbon atoms is used to make candles and paraffin wax with solar energy storage capacity?

Correct option is C

The correct answer is (c) Eicosane.
· Eicosane is an unsaturated aliphatic hydrocarbon with the molecular formula C20H42. It is composed of 20 carbon atoms and is used in various applications including the manufacture of candles and paraffin wax.
· Eicosane has significant utility in solar energy storage due to its phase change material (PCM) properties. It can absorb and release thermal energy during phase transitions (melting and solidifying), making it useful in thermal energy storage systems.
· This compound is particularly valued for its ability to store solar energy and release it when needed, providing an efficient and sustainable energy storage solution.
