If you experience a painful bee sting, there is formic acid at work. which type of organic compound is responsible for your suff
ering?
2 answers:
Answer: Carboxylic acid
Explanation: Bee stings are basically venomous in nature and they do create excruciating pain because they contain Formic acid which belongs to the carboxylic acid group.
Formic acid has a pKa of 3.5 approximately. Thus it is moderately acidic in nature . That is why it is recommended to treat it with some kind of alkali like Baking soda or toothpaste etc.
The structure of the formic acid is displayed in the image attached.

Answer: polar molecule.
Explanation:
The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. The boiling point is dependent on the type of forces present.
Iodine monochloride (ICl) is a polar molecule due to the difference in electronegativities of iodine and chlorine. Thus the molecules are bonded by strong dipole dipole forces. Thus a higher temperature is needed to generate enough vapor pressure.
Bromine is a non polar molecule as there is no electronegativity difference between two bromine atoms. The molecules are bonded by weak vanderwaal forces and thus has low boiling point.
Explanation:
As the total concentration is given as 1.2 mM. And, it is also given that salt present in the solution is NaCl.
As sodium chloride is an ionic compound so, when it is added to water then it will dissociate into sodium and chlorine ions as follows.
So, it means in total there will be formation of 2 ions when one molecules of NaCl dissociates.
Therefore, concentration of chlorine ions will be calculated as follows.
Concentration of ions =
= 0.6 mM
Thus, we can conclude that the concentration of chloride ions is 0.6 mM.
