Hydrostaic hyfrogen bonds h2o
WebOur results reveal that OH is a stronger hydrogen bond donor but a weaker hydrogen bond acceptor than H (2)O. This conclusion is independent of the correction for BSSE and can be rationalized by the NBO analysis, the results of which indicate that OH radical has a lower n (O) and sigma* (O-H) in energy than that of H (2)O. WebThis energy is available at room temperature and hence, hydrogen sulphide is a gas, while water is still a liquid. In water molecule the more electronegative oxygen atom has small …
