Question

Select which arranges the following molecules in order of increasing dipole moment: h2o, h2s, h2te, h2se.

Answer 1

To arrange the molecules h2o, h2s, h2te, and h2se in order of increasing dipole moment, we need to consider the electronegativity difference between the atoms. The larger the difference, the larger the dipole moment. Comparing the electronegativities of the atoms in each molecule, we find that the order of increasing dipole moment is H2S < H2O < H2Se < H2Te.

Step-by-step explanation:

The dipole moment of a molecule is a measure of its polarity. A molecule with a larger dipole moment is more polar than a molecule with a smaller dipole moment. To arrange the given molecules(h2o, h2s, h2te, h2se) in order of increasing dipole moment, we need to consider the electronegativity difference between the atoms.

Dipole moment is directly proportional to the electronegativity difference between the atoms. The larger the electronegativity difference, the larger the dipole moment.

1. h2s: Sulfur (S) and hydrogen (H) are both nonmetals, so we compare their electronegativity values. Sulfur has higher electronegativity than hydrogen, so the dipole moment of h2s is larger than that of h2o.
2. h2o: The electronegativity difference between oxygen (O) and hydrogen (H) is larger than between sulfur (S) and hydrogen (H), so the dipole moment of h2o is larger than h2s.
3. h2se: The electronegativity difference between selenium (Se) and hydrogen (H) is larger than that of oxygen (O) and hydrogen (H), so the dipole moment of h2se is larger than h2o.
4. h2te: The electronegativity difference between tellurium (Te) and hydrogen (H) is larger than that of selenium (Se) and hydrogen (H), so the dipole moment of h2te is larger than h2se.
