The dipole moments of diatomic molecules AB and CD are 10.41D and 10.2...
As dipole moment = electric charge × bond length D. M. of AB molecules = 4.8 x 10 -10 x 2.82 x10 -8 = 13.53D
D.M. of CD molecules = 4.8 x10-10 x 2.67 x10-10 = 12.81D

The dipole moments of diatomic molecules AB and CD are 10.41D and 10.2...
To calculate the partial charge of each atom in the diatomic molecules, we can use the equation:

μ = charge × distance

where μ is the dipole moment, charge is the partial charge on each atom, and distance is the bond distance.

For molecule AB:
μ = 10.41 D
distance = 2.82 Å

Therefore, the partial charge on each atom in molecule AB can be calculated as:

charge = μ / distance
charge = 10.41 D / 2.82 Å

Converting D to Cm (Coulomb meter) and Å to meters:

1 D = 3.336 × 10^-30 Cm
1 Å = 1 × 10^-10 meters

charge = (10.41 D × 3.336 × 10^-30 Cm) / (2.82 × 10^-10 meters)
charge = 3.91 × 10^-19 C

So, the partial charge on each atom in molecule AB is 3.91 × 10^-19 C.

Similarly, for molecule CD:
μ = 10.27 D
distance = 2.67 Å

charge = μ / distance
charge = 10.27 D / 2.67 Å

Converting units:

charge = (10.27 D × 3.336 × 10^-30 Cm) / (2.67 × 10^-10 meters)
charge = 3.84 × 10^-19 C

Therefore, the partial charge on each atom in molecule CD is 3.84 × 10^-19 C.

Attempt All sub parts from each question.Molecular Perspective In water, there are two types of molecules. Some molecules are at the surface, called exterior molecules, and some molecules are inside, called interior molecules. The interior molecules are attracted to all the molecules around them. The exterior molecules are attracted to only the other surface molecules and to those below the surface. So that the energy state of the molecules on the interior is much lower than that of the molecules on the exterior. The molecules always try to maintain a lower energy state and hence the exterior molecules experience a downward force. This force is known as cohesive force. As a result they try to maintain a minimum surface area, thus allowing more molecules to have a lower energy state. Thus surface tension is created. The water molecules attract one another due to the water molecule’s polar property. The hydrogen ends, which are positive in comparison to the negative ends of the oxygen, cause water to "stick " together. This is why there is surface tension. Water has very high surface tension.
