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.

∙ 10y agoThey can be both polar and non-polar. It depends on the symmetry- the bond dipoles may cancel one another out to give a non polar molecule -(CCl4 is an example) CH2Cl2 is polar the bond dipoles do not cancel each other out.

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 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
Why is CH4 molecule non polar?
CH4 is non-polar because its molecular geometry, tetrahedral, is symmetrical.
Is carbon tetrafluoride a covalent or polar covalent or ionic bond?
Polar covalent bonds. Not that due to the symmetry of the molecule (tetrahedral) the bond dipoles cancel each other out and overall the molecule is non-polar.
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 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 CCl4 polar or non pollar?
No. The individual bonds are polar, but the molecule as a whole is symmetric and therefore nonpolar.
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 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
Why is CH4 molecule non polar?
CH4 is non-polar because its molecular geometry, tetrahedral, is symmetrical.
Is carbon tetrafluoride a covalent or polar covalent or ionic bond?
Polar covalent bonds. Not that due to the symmetry of the molecule (tetrahedral) the bond dipoles cancel each other out and overall the molecule is non-polar.
Why is hydrogen peroxide polar?
Hydrogen peroxide is polar due to its angular shape. There are only two cases where a molecule is non-polar, which is when the molecule is pure covalent bond in linear or tetrahedral shape. Hydrogen peroxide is neither therefore it is polar.
Is CHF3 polar or non-polar?
Yes it is and it has a tetrahedral shape
What is the molecule polarity of SiF4?
The Molecule SF4 is Non-polar due to the fact that Fluorine is the most electronegative element in existence. Therefore the fluorine atoms evenly pull the molecule in four directions causing an even pull in the molecule and causing it to be non-polar
Is CBr4 polar or nonpolar?
CBr4 is non polar in structure and nonpolar in bonding while finding the difference of electronegativity
Why a tetrahedral molecule containing four identical bonds can never be a polar molecule?
If there are 4 identical bonds, then there are equal pulls on all four bonds. Equal pulls = non polarity.
