Q1)What kind of chemical bonds determine the properties of polyethylene (a polymer material)? Secondary bonds Covalent bonds Ionic bonds Metallic bonds ......... Q2)What kinds of chemical bonds are present in polyethylene (a polymer material)? Metallic bonds Ionic bonds both secondary and covalent bonds secondary bonds Covalent bondsa. Secondary bonds Solution (1) secondary bonds determine the properties of polyethylene. ,(2) in polyethylene covalent bond hold the atom together and secondary bond hold the chain together to make polymer.
