Question

question 3 (5 points)
which portion of a molecule of f₂o has partial positive charge?
a) the central o atom
b) the partial charge on each atom is negative
c) the f atoms
d) the partial charge on each atom is zero

Explanation:

To determine the portion with partial positive charge in \( \text{F}_2\text{O} \), we analyze electronegativity. Fluorine (F) is more electronegative than oxygen (O). In a covalent bond, the more electronegative atom attracts electrons more, gaining a partial negative charge, while the less electronegative atom (O here) has a partial positive charge. The central atom in \( \text{F}_2\text{O} \) is O, bonded to two F atoms. Since O is less electronegative than F, the central O atom will have a partial positive charge. Option B is wrong as not all atoms have negative charge, option C is wrong as F is more electronegative (partial negative), and option D is wrong as there is a polar bond (so partial charges exist).

Answer:

A) The central O atom
