Question

question 1
(02.01 lc)
the slight negative charge at one end of one water molecule is attracted to the slight positive charge of another water molecule. what is this attraction called?
a hydrogen bond
a covalent bond
an ionic bond
a hydrophilic bond

Explanation:

To solve this, we analyze each option:

• A hydrogen bond: Occurs between a slightly negative atom (like O in water) and a slightly positive hydrogen (in another water molecule), matching the attraction between water molecules' partial charges.
• A covalent bond: Involves sharing electrons (e.g., within a water molecule, H and O), not between molecules.
• An ionic bond: Involves transfer of electrons to form ions, not relevant here.
• A hydrophilic bond: Not a standard bond term; hydrophilic refers to attraction to water, not between water molecules.

Answer:

A. A hydrogen bond
