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 (
