Answer:
Methanol is the simplest alcohol with molecular formula CH3OH. It is also called as methyl alcohol, wood alcohol, wood naphtha or wood spirit. It is a light, volatile, colorless, flammable liquid.
It is used as an antifreeze, solvent, fuel, and as a denaturant for ethanol. It is also used for producing bio-diesel via trans-esterification reaction.
THE PROPERTIES OF ETHONOL
- Ethanol is a colorless liquid having a pleasant smell and a burning taste
- It is a volatile liquid having a low boiling point of 78o C (351 K)
- It is miscible with water in all proportions
- Ethanol does not contain any ions, as it is a covalent compound and has no effect on litmus paper
- The boiling point of alcohols are, in general, much higher than the corresponding alkanes. This is because in alcohols there is intermolecular association of a large number of molecules due to Hydrogen bonding which is absent in alkanes
