Question 1

Which of the following best describes the bond polarity in the molecule shown in the image, using delta notation?

Accepted Answer

The hydrogen atom is labeled $$\delta^+$$ and the fluorine atom is labeled $$\delta^-.$$

Question 2

Why does the fluorine atom in the molecule shown have a $$\delta^-$$ charge?

Accepted Answer

Fluorine is more electronegative than hydrogen, so it attracts electrons more strongly.

Question 3

Which type of intermolecular force is strongest in a sample of the molecule shown in the image?

Accepted Answer

Hydrogen bonding

Question 4

If the molecule shown is dissolved in water, which property of water allows it to interact strongly with this molecule?

Accepted Answer
