BCl3 does fulfill the above two conditions stated as 1 and 2 , also as it is a trigonal planar with degrees apart. Apart from NH3 Ammonia , there are many similar polar molecules. One of them is PCl3. Check out the article regarding the polarity of PCl3. BCl3 is the chemical compound with a sp2 hybridization type. In BCl3, Boron as a central atom consists of three bonded atoms of chlorine with no lone pair of electrons left. To form bonds with chlorine atoms, boron will need three unpaired electrons.
Now, here one electron from the 2s is moved to the 2p level. Now, the hybridization of BCl3 occurs where a 2s and two 2p orbitals of boron will participate in the process to form three half-empty sp2 hybrid orbitals.
The chemical name of BCl3 is boron trichloride which is a combo of boron and chlorine. B and Cl are both nonmetals, so this is a covalent compound. B and Cl form polar bonds but, three such bonds in it have the same bond moments, thus the sum of three vectors comes out to be zero. The molecule becomes nonpolar with covalent bonds. BCl3 is a nonpolar molecule, yes and the B-Cl bonds are polar due to the electronegativity difference between the elements.
Cl has an electronegativity of 3. As the bond movement formed in BCl3 cancels out itself. The Cl atoms are identical and they pull the same amount on B electrons. Hence, Cl atoms will still have a bit more negativity to them but because they are symmetrically arranged the effects will cancel each other out. Hence, it forms polar bonds. The centrally situated boron atom in BCl3 is electron-deficient thus, enabling the molecule to accept an extra pair of electrons and hence, acts as a Lewis Acid.
It is used in the refining of aluminum, zinc, magnesium, and copper alloys to remove traits of nitrides, carbides, and oxides from any molten metal.
It is also used as a soldering flux for alloys of aluminum, tungsten, iron, zinc, and monel metal. The gas Boron Trichloride is reactive enough to serve as a rocket fuel It is a Lewis Acid with polar covalent bonds and is a non-polar molecular compound. However, it is noted that the chemical compound should be carefully handled because on hydrolysis with water and other alcohols it produces hydrogen chloride HCl. The molecular geometry of Boron Trichloride BCl3 is a trigonal planar with asymmetrical charge distribution around the central atom.

The bond angle seen at the lewis structure will help determine the shape. Electronegativity is a measure of the capability of an atom in a molecule to attract shared electrons. Electronegativity is a periodic property affecting valence electrons.
The charge distribution of different atoms attached will determine the polarity or non-polarity of the molecule. There is a separation of positive and negative charges because of the unequal attraction for the bonded valence electrons. B, boron in the periodic table, and Cl have different values in terms of electronegativities. Hence chlorine E. As a result, the B—Cl bond forms polar bonds and carries a finite zero dipole moment. While it is true that BCl3 is non-polar, it forms bonds because the B-Cl bond itself is not non-polar, caused by the difference in electronegativity of Boron 2.
All three valence electrons, B-Cl bonds that are at a distance of degrees from each other, the chemical bond still cancels out, making the net dipole moment zero. Boron trichloride or BCl3 is a combination of two atoms boron and chlorine. B atoms and Cl atoms are both nonmetals making them covalent compounds. As B electrons in BCl3 undergo sp2 hybridization, the resultant shape is trigonal planar. B and Cl form polar covalent bonds, but three other covalent bonds have the same bond moments.
Thus the sum of three valence electrons comes out to be zero dipole moment in a single bond. Boron Trichloride is a reactive gas that can serve as rocket fuel as it produces hydrogen chloride. This is not an ordinary boron atom turned chemical compound because once it is on hydrolysis with water and other alcohols, this can form hydrogen chloride.
The molecular geometry of ICl5 is square pyramid with an asymmetric electron region distribution. Therefore this molecule is polar. BeCl2 Beryllium chloride is non-polar due to its symmetrical linear-shaped geometry.
Due to this difference between the electronegativity of Be and Cl atoms, the Be-Cl bond formed is polar. In other words, the charge distribution across the Be-Cl bond is non-uniform.
CF4 is a nonpolar molecule. Although all C-F bonds are polar because carbon and fluorine differ in their electronegativity, the overall CF4 molecule is non-polar.
This is because of the symmetrical arrangement of all fluorine atoms around the central carbon atom. Releases toxic, corrosive, flammable or explosive gases. If adverse effects occur, remove to uncontaminated area.
