Which of the following compounds, when dissolved in water, will not result in
dissociation?
a. table salt, nacl
b. table sugar, c12h22011
c. baking soda, nahco3
d. epsom salts, mgso4

b. table sugar  (C12H22011)

Table sugar will not dissociate when dissolved in water because of the strong covalent bonds between the carbon, hydrogen and oxygen atoms of sugar molecules.

Table sugar is also a polar molecule but having strong covalent bonds between the carbon, hydrogen, and oxygen atoms which prevent the dissociation into ions in water as compared to salt which readily dissociates so we can say that sugar will not dissociate when dissolve in water.

The answer to your question is: letter B, table sugar.

Explanation:

Molecules that dissociate in water are called salts, they can dissociate partially or totally.

a. table salt, NaCl                       It's a salt, it dissociates

b. table sugar, C12H22011         It's not a salt

c. baking soda, NaHCO3           It's an acid salt, it dissociates

d. Epsom salts, MgSO4            It dissociates    

a electronegativity decreases beacuse the size of nucleus is bigger.
