Although both CO_(2) and H_(2)O are triatomic molecules,the shaep of H_(2)O molecule is bent while that of CO_(2) is linear. Explain this on the basis of dipple moment?

Answer» <html><body><p></p>Solution :`CO_(2)` is a linear in which the two C=O are oriented in the <a href="https://interviewquestions.tuteehub.com/tag/opposite-1137237" style="font-weight:bold;" target="_blank" title="Click to know more about OPPOSITE">OPPOSITE</a> directions at an angle of `180^(@)`. The dipole moment of C=O is 2.3 D due to linear <a href="https://interviewquestions.tuteehub.com/tag/structure-1230280" style="font-weight:bold;" target="_blank" title="Click to know more about STRUCTURE">STRUCTURE</a> of `CO_(2)` the bond <a href="https://interviewquestions.tuteehub.com/tag/dipoles-440066" style="font-weight:bold;" target="_blank" title="Click to know more about DIPOLES">DIPOLES</a> of two C=O bonds <a href="https://interviewquestions.tuteehub.com/tag/cancel-406753" style="font-weight:bold;" target="_blank" title="Click to know more about CANCEL">CANCEL</a> with each other. Therefore resultant `mu` is zero. <br/> On the other hand `H_(2)O` is polar molecule having dipole moment 1.54 D. Actually `H_(2)O` molecule has bent structure in which O-<a href="https://interviewquestions.tuteehub.com/tag/h-1014193" style="font-weight:bold;" target="_blank" title="Click to know more about H">H</a> bonds are oriented at an angle of `104^(@)5^(1)` and dont cancel the bond moment of each other.</body></html>
