Question

A compound that is capable of forming hydrogen bonds with water
A.is probably held together by noncovalent bonds
B. contains at least some polar covalent bonds
C. should act as a good buffer for acids and bases
D. does not dissolve well in water

Answer 1

A compound that is capable of forming hydrogen bonds with water is (B) contains at least some polar covalent bonds

Explanation:

1.A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei.

2. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

3.An example is water. Water consists of a covalent bond containing hydrogen and oxygen bonding together to make H2O.

4.In this atomic molecule, two hydrogen atoms share their single electrons with the oxygen atom, which shares its own two electrons in return.
