Yes, they generally are. In the case of ammonia, NH3, nitrogen has an electron pair and three unpaired electrons (as per Hund's rule.) The pair remains unbonded, but each single electron bonds single-covalently to a hydrogen. The unbonded pair "pushes" the 3 bonded hydrogens downward into a "tripod" shape, making the molecule pyramidal. The molecule is polar because the unbonded pair constitutes a negative partial charge.
What else can I help you with?
Is TeCl4 polar or non-polar?
TeCl4 is a non-polar molecule. The molecule's symmetrical tetrahedral shape and similar electronegativities of chlorine and tellurium atoms result in a balanced distribution of charge, making the molecule non-polar.
Is SeCl4 polar or non-polar?
SeCl4 is a non-polar molecule because the dipole moments of the individual Se-Cl bonds cancel each other out due to the symmetric tetrahedral shape of the molecule.
Is CCl4 polar or non pollar?
No. The individual bonds are polar, but the molecule as a whole is symmetric and therefore nonpolar.
Is the molecule Cl2C equals CCl2 polar or non polar?
CCl4 is a non polar molecule because though each of the C-Cl bond is polar but the resultant of all these dipole moments is zero as its a symmetrical tetrahedral shape molecule ,and their is a cancellation of dipole moment in each pair
Is ph4 a dipole?
No it's not. It is non-polar since it has a geometrical shape of a tetrahedral. Tetrahedral geometries are symmetrical, so even if P-H is polar bond, they get cancelled out resulting in a non-polar molecule
Is TeCl4 polar or non-polar?
TeCl4 is a non-polar molecule. The molecule's symmetrical tetrahedral shape and similar electronegativities of chlorine and tellurium atoms result in a balanced distribution of charge, making the molecule non-polar.
Is POOH'S polar or non polar?
The geometry of PO(OH)3 is tetrahedral with an unsymmetric charge distribution.Therefore this molecule is polar.
Is SeCl4 polar or non-polar?
SeCl4 is a non-polar molecule because the dipole moments of the individual Se-Cl bonds cancel each other out due to the symmetric tetrahedral shape of the molecule.
Is AlH4- polar or non polar?
GeH4 is tetrahedral- (same as methane) - any polarity in the Ge-H bonds cancels each other out - do the molecule is non-polar.
Is CCl4 polar or non pollar?
No. The individual bonds are polar, but the molecule as a whole is symmetric and therefore nonpolar.
Is the molecule Cl2C equals CCl2 polar or non polar?
CCl4 is a non polar molecule because though each of the C-Cl bond is polar but the resultant of all these dipole moments is zero as its a symmetrical tetrahedral shape molecule ,and their is a cancellation of dipole moment in each pair
Is ph4 a dipole?
No it's not. It is non-polar since it has a geometrical shape of a tetrahedral. Tetrahedral geometries are symmetrical, so even if P-H is polar bond, they get cancelled out resulting in a non-polar molecule
Is hydrogen a non-polar molecule?
yes it is a non polar molecule
Is SO4 2- polar or nonpolar?
The sulfate ion (SO4 2-) is a symmetrical molecule, with a tetrahedral arrangement of atoms around the sulfur. This symmetry cancels out the dipole moments of the individual bonds, resulting in a nonpolar molecule overall.
Is CHF3 polar or non-polar?
CHF3 (trifluoromethane) is a non-polar molecule. This is because the fluorine atoms are symmetrically arranged around the central carbon atom, resulting in a symmetrical distribution of charge and no overall dipole moment.
Is chloroform non-polar?
Yes. the dipole moments cancel each other out in the tetrahedral arrangement
Is xenon tetrafluoride polar?
No. Carbon tetrafuoride is a non polar molecule but with polar covalents bonds. the polar covalent bonds sort of cancel each other out on each opposite side (because of it's symmetry) making it non polar overall. (CF4 is tetrahedral)
