Question

which of these is the correct lewis structure for hydrogen peroxide, h₂o₂? images of lewis structure options are present

Explanation:

Step1: Recall Lewis Structure Rules

Hydrogen peroxide (\(H_2O_2\)) has a structure with two O atoms connected by a single bond, each O bonded to an H. Each O has 2 lone pairs (total 4 non - bonding electrons, or 2 pairs) to satisfy the octet (O needs 8 electrons: 2 from the O - O bond, 2 from O - H bond, and 4 as lone pairs).

Step2: Analyze Each Option

• First option: The structure has two O atoms, each bonded to an H and connected through an H? No, \(H_2O_2\) is \(H - O - O - H\), not with an H between the two O - H groups. Wait, no, re - examining: Wait, the third option (the one with the two O atoms connected, each with an H and lone pairs). Wait, let's count electrons. For \(H_2O_2\), total valence electrons: \(2\times1 (H)+2\times6 (O)=14\).
• Let's check the third option (the one with \(H - \overset{\cdot \cdot}{O}-\overset{\cdot \cdot}{O}-H\), with each O having 2 lone pairs). Wait, no, the correct Lewis structure for \(H_2O_2\) is \(H - O - O - H\), where each O has 2 lone pairs (4 electrons) and the bonds: O - H (single bond, 2 electrons), O - O (single bond, 2 electrons). So each O has \(2 (from O - O)+2 (from O - H)+4 (lone pairs)=8\) electrons.
• The third option (the one in the middle - third, with the two O atoms connected, each bonded to an H and having lone pairs) is the correct one. Wait, looking at the options: the third option (the one with \(H - \overset{\cdot \cdot}{O}-\overset{\cdot \cdot}{O}-H\) - no, the third option as per the list: the third circle - the structure is \(H - O\) (with lone pairs) and \(O - H\) connected by a bond between the two O's. Yes, that's \(H - O - O - H\), with each O having 2 lone pairs. So that's the correct Lewis structure. Wait, the original options: let's re - index. The first option has an H between the two O - H groups (incorrect, as \(H_2O_2\) is \(H - O - O - H\), not \(H - O - H - O\) with an H in the middle). The second option has \(O - H - O - H\) (incorrect, O and O should be bonded). The third option has \(H - O - O - H\) with each O having lone pairs (correct). The fourth option has a square - like structure (incorrect, as \(H_2O_2\) is linear in terms of the O - O - H chain, not cyclic). So the third option (the third circle) is correct. Wait, the user's image: the third option (the one with \(H - \overset{\cdot \cdot}{O}-\overset{\cdot \cdot}{O}-H\) - the structure where the two O atoms are bonded to each other and each to an H, with lone pairs on each O).

Answer:

The third option (the one with the structure \(H - \overset{\cdot \cdot}{O}-\overset{\cdot \cdot}{O}-H\) where the two oxygen atoms are bonded together and each is bonded to a hydrogen atom, with lone pairs on each oxygen)
