Do you think the following is a valid statement? "The greater the electronegativity difference between the atoms in a molecule, the greater the dipole moment is." Explain.

It is true for individual bonds, but not for molecules.
The dipole moment of the molecule will depend on the geometry of the polar covalent bonds. E.g. CF4 has 4 polar bonds but they arranged so that the sum of their dipole moments is zero and the molecule has actually no dipole moment.

The -ols do, the -anes don't. An oxygen atom at one end of the molecule will give it a dipole moment.

Not true.
The distance between the atoms is just as important. Remember that the dipole moment is proportional to charge time distance.

yes because it means that the other atom has much more negative energy than the other one which is becoming more positive. also known as permanent dipole
