Which of the following will dissolve in polar solvents?
a) non-polar solvents and ionic compounds
b) ionic compounds and polar covalent compounds
c) non-polar solvents and covalent compounds
d) All of the above
Plss
The correct answer is b) ionic compounds and polar covalent compounds.
Polar solvents, such as water, have a partial positive charge on one end and a partial negative charge on the other end. These charges allow polar solvents to interact with other polar molecules or ionic compounds, which have positive and negative charges.
Non-polar solvents and covalent compounds, on the other hand, do not have charges that can interact with polar solvents. Therefore, they do not dissolve in polar solvents.
So, only ionic compounds and polar covalent compounds will dissolve in polar solvents.
To determine which of the following will dissolve in polar solvents, we need to remember the principle that "like dissolves like." This means that substances with similar polarity will dissolve in each other. Now let's break down the options:
a) Non-polar solvents and ionic compounds: Non-polar solvents, being non-polar, will not readily dissolve in polar solvents. Ionic compounds, on the other hand, consist of positive and negative ions and readily dissolve in polar solvents due to their charged nature. So, this option is incorrect.
b) Ionic compounds and polar covalent compounds: As mentioned earlier, ionic compounds dissolve in polar solvents due to their charged nature. Polar covalent compounds, which have a partial positive and negative charge distribution, also dissolve in polar solvents. Therefore, this option is correct.
c) Non-polar solvents and covalent compounds: Non-polar solvents do not dissolve in polar solvents, as they have different polarities. Covalent compounds, which share electrons between atoms, can be either polar or non-polar. While polar covalent compounds dissolve in polar solvents, non-polar covalent compounds do not. So, this option is incorrect.
d) All of the above: As we have discussed, option a and c are incorrect. Therefore, the correct answer is not "All of the above."
In conclusion, the correct answer is b) ionic compounds and polar covalent compounds, as they both have the ability to dissolve in polar solvents.
