Alcohol is an example of an organic compound that contains an attached hydroxyl group.
Ester has the general formula of RCOOR'.Where R and R' can be same or different alkyl groups.
Alcohol has hydroxl group which act as functional group in alcohols attached to carbon chain.
They have general formula of ROH. Where R is an alkyl group.
Aldehydes has carbonyl group which act as functional group in aldehydes attached to carbon chain from only one side .
They have general formula of R-CHO. Where R is an alkyl group.
Ketones has carbonyl group which act as functional group in ketones, attached to carbon chains from both the sides .
They have general formula of R-(CO)-R'.Where R and R' can be same or different alkyl groups.
The correct answer is the second option. Alcohol is the organic compound which is attached to a hydroxyl group. This group is a functional group which consists of a hydrogen atom bonded covalently to an oxygen atom which is found in sugars and alcohols.
As the temperature of a solvent increases, the solubility of any gas dissolved in that solvent decreases.
when the temperature of a river, lake or stream is raised high , due to discharge of hot water from some industrial process the solubility of the oxygen in the water is decreased .The fish and the other organisms that live in the water bodies such as rivers, ponds, lakes etc can survive only in the presence of oxygen and decrease in the concentration of the water due to increased temperature can lead to the death of the fish and this may in turn damage the ecosystem.
In the above example, water is considered as the solvent and the oxygen is considered as the solute. When the temperature of the solvent that is water increases, the solubility of the gas that is oxygen in the solvent decreases.
Therefore the answer is decreases.
Negative is it can't be broken down and makes the air polluted. Positive, it can be re used again and again.
