Which is the most accurate description of compounds?
2 answers:
Answer: Option (d) is the correct answer.
Explanation:
A compound is defined as the substance in which only different atoms chemically combine together in a fixed ratio by mass.
For example, NaCl, HCl, , etc are all compounds.
Compounds are also pure substances like elements as they can be broken down into their constituent particles.
Whereas substances that are made up of only one type of atom are known as elements.
Thus, we can conclude that the most accurate description of compounds is that they are made up of atoms of 2 or more elements that are chemically combined.

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.
