Answer 3

Thanks
Can u pls explain it also

Answer 4

It is because metals have strong metallic bonds and ionic compounds as well, involving for both of them attractions between cations and anions.
SiO2 is very strongbecause the arrangemt is gian covalent, making the compund incredibly strong. That organic compound has simple molecular covalent bonds within the atoms and alsoth bonds that caron makes with the oxygen atoms are unsaturated and these are very weak bonds, because pi bonds ar relatively vulnerable to reactions.
