Ответ:
A
Explanation:
Using the equation above, the dipole moment is calculated to be 1.85 D by multiplying the distance between the oxygen and hydrogen atoms by the charge difference between them and then finding the components of each that point in the direction of the net dipole moment (the angle of the molecule is 104.5˚).

According to lewis concept,
Acids are species which can accept electrons
bases are species which can donate electron pair
Acc. to Lowry-Bronsted concept,
Acids are species which can donate hydrogen atom
So,BF3,AlCl3 and PCl5 are acids according to Lewis bcuz they have the tendency to accept electrons but accord to Bronsted concept they can`t donate a hydrogen atom.
