The characteristics of two unknown intermolecular forces, C and D, are compared in the table. Intermolecular Forces
CD
Occurs between polar asymmetrical moleculesOccurs between non-polar or polar symmetric molecules

Which of the following conclusions about the two intermolecular forces is correct? (1 point)

a
C represents ion-dipole forces, and D represents dipole-dipole forces

b
C represents dipole-dipole forces, and D represents London dispersion forces

c
C represents London dispersion forces, and D represents ion-dipole forces

d
C represents hydrogen bonding, and D represents London dispersion forces

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

the answer is a for sure mark brainliest i had got this right on usatestprep
