T-Shape Polarity

[Joey_Okumura_1E]

Is every molecule that is arranged in a T-shape polar?

[Gina Spagarino 3G]

T shape will always mean polar... of the different trigonal bipyramidal orbital arrangements with the sp³d hybridization, only the trigonal bipyramidal with 5 attached atoms or the linear model with 2 bonded atoms and 3 lone pairs can be nonpolar given that their bonded atoms are the same.

Hi! I agree with the above post that every molecule that has a T-shape will be polar. Out of the four molecular shapes with 5 electron domains/density regions, two will always be polar: T-shape and see-saw. This is because the lone pairs of each cause an asymmetrical arrangement (dipole moments won’t cancel out). I hope this helps!

Yes, it will. The dipoles will never cancel out so there will always be an unequal sharing of electrons.

Yes, like the posts above mentioned, the dipoles wont ever cancel out so there will always be an unequal sharing of electrons as the lone pairs cause an asymmetrical shape where the dipoles still exist.
