If the elements W, X, Y, and Z have electronegativity values of 1.0, 2.0, 2.5, and 3.5, respectively, which bond is the least polar

Answer:

XY bond is the least polar

Explanation:

Given

[tex]W = 1.0[/tex]

[tex]X = 2.0[/tex]

[tex]Y = 2.5[/tex]

[tex]Z = 3.5[/tex]

Required

The least polar bond

First, we calculate the difference in the electronegativities

[tex]WX = X - W[/tex]

[tex]WX = 2.0 - 1.0[/tex]

[tex]WX = 1.0[/tex]

[tex]WY = Y - W[/tex]

[tex]WY =2.5 - 1.0[/tex]

[tex]WY =1.5[/tex]

[tex]WZ =Z-W[/tex]

[tex]WZ =3.5 - 1.0[/tex]

[tex]WZ =2.5[/tex]

[tex]XY = Y -X[/tex]

[tex]XY = 2.5 -2.0[/tex]

[tex]XY = 0.5[/tex]

[tex]XZ = Z -X[/tex]

[tex]XZ = 3.5 -2.0[/tex]

[tex]XZ = 1.5[/tex]

[tex]YZ = Z - Y[/tex]

[tex]YZ = 3.5 - 2.5[/tex]

[tex]YZ = 1.0[/tex]

The least of the above calculations will be the least polar.

Hence, XY is the least polar
