HSO is an intermediate in the atmospheric oxidation of H 2 S, and it has been implicated
Question:
HSO is an intermediate in the atmospheric oxidation of H2S, and it has been implicated in ozone depletion. Calculated wavenumbers for the fundamental modes of vibration of HSO are 2335, 1077 and 1002 cm−1. These are assigned to stretching, bending and stretching modes, respectively. Deuteration causes the fundamental modes of vibration to shift to 1704, 772 and 1041 cm−1.
(a) Is the HSO molecule linear or bent?
(b) Draw one or more resonance structures to describe the bonding in HSO.
(c) How many of the fundamental modes of vibration are IR active?
(d) Which of the modes of vibration (2335, 1077 or 1002 cm−1) arises from the S–H stretch? Use the deuteration data to confirm your assignment.
(e) Suggest why HSO is associated with ozone depletion.
Step by Step Answer:
a To determine if the HSO molecule is linear or bent we can use the information about its fundamental modes of vibration In a linear molecule there is ...View the full answer
