Wax used for making candle is chemically a mixture of – |
| A. | aliphatic hydrocarbons |
| B. | aromatic hydrocarbons |
| C. | cyclic hydrocarbons |
| D. | aliphatic and aromatic hydrocarbons |
| Answer» A. aliphatic hydrocarbons | |
|
Explanation: An aliphatic compound is a hydrocarbon compound containing carbon and hydrogen joined together in straight chains, branched trains or non-aromatic rings. Waxes are a class of chemical compounds that are plastic (malleable) near ambient temperatures. Characteristically, they melt above 45 degree C (113 degree F) to give a low viscosity liquid. Waxes are insoluble in water but soluble in organic, non-polar solvents. All waxes are organic compounds, both synthetic and naturally occurring. Waxes are organic compounds that characteristically consist of long alkyl chains. |
