Hydrogen bonds:
a) form between two hydrogen atoms.
b) form only between hydrogen and oxygen atoms within a molecule.
c) form only between a weak electronegative atom and hydrogen.
d) involve a transfer of electrons.
e) form weak interactions but can provide structural stability when many are found in a single molecule.

Option e.

Explanation:

The option 'e' fact about Hydrogen bonds are correct, that is; ''form weak interactions but can provide structural stability when many are found in a single molecule''.

So, what is this Hydrogen bond?

Hydrogen bonds is a kind of strong dipole- dipole attractions. Hydrogen bonding occurs as a result of the bonding between hydrogen and strongly electronegative atoms for example oxygen, Fluorine and so on.

Since we now know what Hydrogen bond is, let us take a look at the options.

(a) for the first option, we can see from above meaning of Hydrogen bonds that Hydrogen bonds occur between Hydrogen and a strong Electronegative atom. So, this option is wrong.

(b). Option 'b' is also wrong Because Hydrogen bonds does not occur between hydrogen and oxygen atoms ONLY but also with other strong Electronegative atoms such as oxygen.

(c). Option 'c' is wrong because between a strong and not only between a weak electronegative atom and hydrogen.

(d). Option 'd' is also not correct.

(e). Option 'e' is correct. Hydrogen bonds contribute to the effect of boiling and melting point of substance, solubilty, dimerization, strength of bonds, shape of molecules and so on

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
