Interpretation:
The compound(s) that are more soluble in water has to be predicted from the following options –
Concept Introduction:
Solubility of a substance depends on various factors like – chemical structure of the substance, temperature, pH etc,
Like dissolves like is a Universal rule which states that polar compounds dissolve more in polar solvents and non-polar compounds dissolve more in non-polar compounds.
Dipole moment is the measure of polarity in polar covalent compounds.
Answer to Problem 12.1KSP
Options (a), (d) and (e) are correct answers.
Explanation of Solution
Reason for correct answers:
The compound given in the options (a), (d) and (c) are polar compounds and so they dissolve in water which is a polar solvent.
The compound given in option (a) is methanol. It is a polar covalent compound as the
Figure 1
The compound given in option (d) is cis-1,2-dichloroethene. The
The compound given in option (e) is Potassium iodide and it is an ionic compound made of
Reasons for Incorrect answers:
The compounds given in options (
Figure 2
Though the
Therefore polarity of the compound gets cancelled.
Figure 3
The compound(s) that are more soluble in water has been predicted from the given options.

- Differentiate between the surface tension of water and that of alcohol. You’ve seen small insects walk on water. Would they be able to walk on alcohol? Explain your answer. No plagarism please!arrow_forwardConsider the following molecules: Na2O, HCl, NH3, N2, CH3CH2OH. Which would have the highest viscosity? please follow below steps to answer the question. Indicate a 'plan' on how you intend to solve YOUR problem. You should have a numerical list. These can be phrases (not complete sentences) if you want, as long as the material is sufficiently easy to follow. Steps should be detailed. For example, "look in the book for the equation" does not work as you could not use that step while taking exams. Show the step by step solution of the problem. Using your plan, (and labeling each step), solve your predicted exam question. Show your work. For example, if you have a scientific notation question, you CANNOT say "move the decimal" but must illustrate each step of the process. If one step requires dimensional analysis to solve you can show your set up using arrows like I do in our videos - but show all of your work. Explain each step of your process. Arrive at the answer in…arrow_forwardThe temperature inside a pressure cooker is 115 C. Calculate the vapor pressure of water inside the pressure coker.
