Calcium bromide>sodium bromide> Butanoic acid>sugar is the order of electrical conductivity.
Organic compounds are generally poor conductors of electricity due to the presence of covalent bonds between atoms. However, some organic compounds can display electrical conductivity in certain conditions. The rank of organic compounds based on their conductivity depends on the type of compound, the environment, and the applied voltage.
In general, organic compounds with a higher number of conjugated double bonds or a higher number of free electrons tend to have higher conductivity. The presence of polar groups, such as alcohols and carboxylic acids, can also increase the conductivity of organic compounds.
In this case, butanoic acid has a carboxylic acid group in it making it a strong acid than sugar.
Likewise, Calcium bromide is more electrically conductive than sodium bromide. This is because calcium bromide contains two positively charged ions (Ca2+ and Br-), while sodium bromide contains only one (Na+ and Br-). The presence of two positive ions allows calcium bromide to form stronger ionic bonds, which makes it more conductive than sodium bromide.
Therefore the correct order of conductivity is, Calcium bromide>sodium bromide> Butanoic acid>sugar.
