P-F is Polar
P-F is Polar
A polar bond occurs when there is an unequal sharing of electrons between two atoms due to differences in electronegativity. In the given examples: F-F and Cl-Cl bonds are nonpolar because they have identical atoms sharing electrons. H-F and H-Cl bonds are polar due to the difference in electronegativity between hydrogen and fluorine/chlorine. P-S bond may be polar or nonpolar depending on the electronegativity of phosphorus and sulfur.
Yes, PF3 is a nonpolar molecule. The molecule has a trigonal pyramidal shape with the fluorine atoms positioned symmetrically around the phosphorus atom, resulting in a net dipole moment of zero.
Polar. Fluorine compounds are almost always polar (except F-F)
In order to determine the polarity of the bond we must first look at the difference of electronegativity. Below are the values of electronegativity: Chlorine: 3.0 Iodine: 2.5 Bromine: 2.8 Fluorine: 4.0 Now we look at the difference (subtract the lower number from the higher number): Cl-Cl=0 Br-I=0.3 F-I=1.5 F-Cl=1.0 Now that we have the difference of electronegativity, we can examine the evidence. Keep in mind that the higher the number, the more polar the bond will be. In this case the most polar bond would be the Flourine-Iodine bond as it has a difference of electronegativity of 1.5, meaning that it is extremely polar.
the f-p-f bond angle is 120the cl -p-cl bond angle is 180and the f - p - cl bond angle is 90
Polar covalent. There is a significant difference in electronegativity between C and F.

PCl3 has a pyramidal geometry, with three polar P-Cl bonds and one lone pair of electrons. Hence the molecule is polar.
If the polar coordinates of a point P are (r,a) then the rectangular coordinates of P are x = rcos(a) and y = rsin(a).
