Write the correct Lewis dot structure for O2. Which statement correctly describes the structure of the whole molecule?
A. There is a single bond, a double bond, and six lone pairs.
B. There is a single bond and four lone pairs.
C. There is a single bond and six lone pairs.
D. There is a double bond and six lone pairs.<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is D. There is a double bond and six lone pairs.<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

To draw the Lewis dot structure for the O\u2082 molecule, we first need to understand the bonding and electron arrangement.<\/p>\n\n\n\n

    \n
  1. Count the total number of valence electrons:<\/strong>
    Oxygen (O) is in Group 16 of the periodic table, meaning each oxygen atom has 6 valence electrons. Since there are two oxygen atoms in O\u2082, the total number of valence electrons is:
    [
    6 \\, (\\text{valence electrons for O}) \\times 2 = 12 \\, \\text{valence electrons}.
    ]<\/li>\n\n\n\n
  2. Form the bond:<\/strong>
    The two oxygen atoms will share electrons to form a covalent bond. A single bond consists of two shared electrons. However, because each oxygen atom needs to fulfill the octet rule (eight electrons around each atom), a single bond is not sufficient. We need to form a double bond (a bond involving four shared electrons). This gives each oxygen atom a total of 8 electrons in its valence shell.<\/li>\n\n\n\n
  3. Place the lone pairs:<\/strong>
    After forming the double bond, we have used 4 electrons for the bond. There are 12 total electrons to place, so 8 electrons remain. These 8 remaining electrons will be placed as lone pairs on the oxygen atoms. Each oxygen atom will have 2 lone pairs of electrons (4 electrons), leaving 4 electrons remaining. These 4 electrons will be placed as a lone pair on each oxygen atom, completing the octet for both atoms.<\/li>\n\n\n\n
  4. Final structure:<\/strong><\/li>\n<\/ol>\n\n\n\n
      \n
    • The two oxygen atoms are connected by a double bond.<\/li>\n\n\n\n
    • Each oxygen atom has two lone pairs of electrons.<\/li>\n\n\n\n
    • Therefore, the structure is O=O<\/strong>, with six lone pairs of electrons in total (four on the two oxygen atoms and two from the double bond electrons).<\/li>\n<\/ul>\n\n\n\n

      Thus, the correct description of the Lewis structure is D. There is a double bond and six lone pairs<\/strong>.<\/p>\n\n\n\n

      Further clarification:<\/h3>\n\n\n\n

      In the O\u2082 molecule, the bonding is a double bond<\/strong>, which consists of one sigma bond and one pi bond. Each oxygen atom also has two lone pairs. This gives a stable configuration where both atoms achieve an octet of electrons.<\/p>\n","protected":false},"excerpt":{"rendered":"
