Question

Which end of the H-F molecule will be partially positive?

neither end
the fluorine end
both ends
the hydrogen end

Answer 1

Hydrogen fluoride (HF) is a polar molecule with partial positive and negative charges on different ends. The fluorine end of the molecule is partially negative, while the hydrogen end is partially positive.

Step-by-step explanation:

Hydrogen fluoride (HF) is a polar molecule, meaning it has partial positive and negative charges on different ends. The fluorine end of the molecule will be partially negative because fluorine is more electronegative than hydrogen. On the other hand, the hydrogen end of the molecule will be partially positive. This polarity is due to the difference in electronegativity between the two atoms.

Answer 2

the hydrogen end

Step-by-step explanation:

In H - F molecules there is a charge separation. Hydrogen has partial positive charge on them and Fluorine has a partial negative charge on it.

• The bonds between H - F molecule is a covalent bond.
• In this bond, both atoms share their electrons to attain a stable configuration
• But the electrons are not shared equally.
• Fluorine is more electronegative compared to the hydrogen.
• Fluorine therefore, attracts the shared electrons more closely to itself.
• This makes fluorine more negative and hydrogen positive.
