1. Explain using diagram how monomers are arranged in Thermoplastic and Thermosettingplastics.​

Explanation:

In thermoplastics, the arrangement of monomeric units is linear and in thermosetting plastics, it is cross-linked. Thermoplastics are usually soft, weak and less brittle, so can get soften on heating and stiffen on cooling. They can be melted, remoulded and recycled easily.
