What type of bond will form between the following pairs of atoms? H and F
Fe and S
Na and O
Si and O
Cl and Cl
Mg and O

the answer is ionic

Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. ... The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion). A brief treatment of ionic bonds follows

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
