In ethanol which part describes its chemical n physical properties
Answers
Pure ethanol is a flammable, colorless liquid with a boiling point of 78.5° C. Its low melting point of -114.5° C allows it to be used in antifreeze products. It has a pleasant odor reminiscent of whiskey. Its density is 789 g/l about 20% less than that of water
general length of the carbon chain determines the physical properties of Carbon chain. As the molecules differ in number of carbon atoms they will differ in physical properties.
Molecules with different number of carbon atoms exists in different states.
Ex: C2H6 is a gas in nature
C6H12: is a liquid
Both C2H6 and C6H12 differ in state, boling point.
And Chemical properties depends up on the functional group present in the molecule.
Ex: Alcohols(R-OH) are differ in chemical properties from carboxylic acids (R-COOH) in reaction with Sodium hydroxide.
Alcohols contains hyxdroxy functional group (-OH) where as carboxylic acids contains acid functional group (-COOH). Thus presence of different functional makes differ in the chemical properties.
