Answer:
BrCl3
Explanation:
BrCl3: This compound has a T- shaped molecular geometry. And the difference in electronegativity is 0.2 to be precise makes is polar covalent compound.
CS2: Carbon sulphide is clearly a non polar compound because of the similar electronegativities of both carbon and sulphur.
SiF4: This molecule has Tetrahedral geometry. So, even though the difference in the electronegativity of Sulphur and Florine is high, the tetrahedral geometry makes it a non polar compound.
SO3: This molecule has trigonal planer geomtry. Hence, again in this molecule the polarity is being equal and opposite is cancelled out.
Answer:
The polarity of the molecule is defined as ability of the molecule to attract water through hydrogen bonding. Polarity of a molecule determines several characteristics of a substance. In the given examples, Bromine trichloride is a polar molecule.
Explanation:
Polarity of the substance or molecule is defined as the ability of a molecule to have electric dipole moment due to distribution of charges. In the given examples:
1. Bromine trichloride has a T-shaped geometry and the difference in electronegativity is 0.2. It has two lone pairs due to which the shape of molecule is bent.
2. Carbon sulphide is a non-polar molecule because of the symmetric shape having no electric dipole moment.
3. The tetrahedral geometry and symmetry of silicon tetrafluoride molecule provides the non-polar characteristic to the molecule. Silicon tetrafluoride have zero net dipole moment.
4. Sulphur trioxide is a non-polar molecule, which have trigonal planar geometry. The polarity of the molecule is cancelled out, which makes it to have zero dipole moment. Thus, it is a non-polar molecule.
