1 Chemical Bonding and Molecular Structure
Which bond angle around X would result in the maximum dipole moment for the triatomic molecule XY2?
1) q = 120o
2) q = 150o
3) q = 90o
4) q = 180o
SOLUTION
The dipole moment of two dipole inclined at an angle θ is given by the equation μ=√(X2+Y2+2XYcosθ) cos90?=0. Since the angle increases more and more−ve-ve and hence resulant decreasd. Thus dipole moment is maximum when θ=90?.
