Answer:
attached here is the diagram of the solution
Explanation:
Answer: 
Explanation:
Geometrical symmetry of the molecule and the polarity of the bonds determine the polarity of the molecule.
The molecule that has zero dipole moment that means it is a geometrically symmetric molecule and the molecule which has some net dipole moment means it is a geometrically asymmetric molecule.
As the molecule is symmetric, the dipole moment will be zero as dipole moments cancel each other and the molecule will be non-polar.
As the molecule is asymmetric, the dipole moment will not be zero and the molecule will be polar.
Example: 
Thus, we can say that
is a polar molecule.
The answer is A i think if it’s wrong someone correct me
he is a good scientist because he postulated that chemical reactions resulted in the rearrangement of the reacting atoms
B. Fluorine (F) is the right answer
