Question

Polar attractions are ...

(a) forces between atoms with partial charges.
(b) weaker than covalent bonds.
(c) important because they are numerous.
(a) and (b) are true. (c) is false.
(a), (b), and (c) are correct.

Answer 1

Polar attractions, also known as dipole-dipole interactions or polar interactions, relate to the attraction between molecules that have permanent dipoles. Let's analyze the statements:

(a) **Forces between atoms with partial charges** - This is true because polar molecules have regions of partial positive and negative charges due to the unequal sharing of electrons.

(b) **Weaker than covalent bonds** - This is also true. Polar attractions are generally much weaker than covalent bonds, which involve the sharing of electrons between atoms.

(c) **Important because they are numerous** - This is true as well. While each individual polar attraction is relatively weak, the cumulative effect of many such attractions in a substance (like water) can be significant.

Given this analysis, the correct response would be:

**(a), (b), and (c) are correct.**
