CHÚCHO (4 = 10% DỊ HCOOH W 1410) Осн,сосна и 2 во CH,CI 160 DI Question 8 4 pts What types of intermolecular forces exist between HF molecules?

Answer 1

6) with decreasing the number of carbon atoms in the main chain, dispersion force decreases.

CH3OCH3 have two C atoms.

Hence

answer: CH3OCH3

7) with increasing the dipole moment, dipole-dipole interaction increases.

CH3COCH3 have highest dipole moment.

so

answer is CH3COCH3

8) HF contains H and F atoms.

due to higher electronegativity difference between H and F, HF take part is hydrogen bonding among HF molecules.

Besides hydrogen bonding there are also dipole-dipole interaction

but hydrogen bonding is the primary intercation among HF molecules.
