Question

determine the molecular geometry of h₂s. trigonal planar tetrahedral bent linear trigonal pyramidal

Explanation:

To determine the molecular geometry of \(H_2S\), we first look at the central atom \(S\). Sulfur has 6 valence electrons. In \(H_2S\), it forms 2 single bonds with hydrogen atoms (using 2 of its valence electrons). This leaves \(6 - 2=4\) valence electrons, which form 2 lone pairs. According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, for a molecule with a central atom having 2 bonding pairs and 2 lone pairs, the molecular geometry is bent. Trigonal planar requires 3 bonding pairs and no lone pairs on the central atom. Tetrahedral is the electron - pair geometry (considering both bonding and lone pairs) for a central atom with 4 electron pairs (but not the molecular geometry when there are lone pairs). Linear is for a central atom with 2 bonding pairs and no lone pairs (like \(CO_2\)). Trigonal pyramidal is for a central atom with 3 bonding pairs and 1 lone pair.

Answer:

bent
