Answer 1

DNA has hydrogen bonds holding the two strands that form the double helix together and covalent bonds in between the nucleotides of each strand.

Ice has hydrogen bonds which attract the water molecules to form the lattice structure of ice and covalent bonds that hold the hydrogen atoms and oxygen atoms together to form H2O

Inorganic compounds (without organic carbon) such as acids and salt, NaCl, have ionic bonds, iron pyrite, PbS, has a metallic bond, water, H2O has covalent bonds and hydrogen bonds.

Sorry there is no one answer for each substance
