Low density polythene (LDPE) is a type of polyethylene polymer. Let's analyze each statement to identify the false one.

Statement 1: "Its synthesis requires dioxygen or a peroxide initiator as a catalyst." This is TRUE. LDPE is produced by the free-radical polymerization of ethylene. The reaction is initiated by small amounts of oxygen or organic peroxides, which generate free radicals to start the chain reaction.

Statement 2: "Its synthesis requires high pressure." This is TRUE. The free-radical polymerization process for LDPE is carried out at high pressures (around 1000-3000 atm) and high temperatures (around 350-570 K). These conditions are necessary to facilitate the reaction and achieve the desired branched structure.

Statement 3: "It is used in the manufacture of buckets, dust-bins etc." This is FALSE. Buckets and dustbins are typically made from high-density polythene (HDPE), which is more rigid and has a higher tensile strength. LDPE is a softer, more flexible material. Its common uses include plastic bags, squeeze bottles, film wraps, and flexible containers.

Statement 4: "It is a poor conductor of electricity." This is TRUE. Like most polymers, LDPE is composed of long-chain hydrocarbons and is an excellent electrical insulator. It does not have free electrons or ions to conduct electricity.

Polymerization: The process of combining small molecules (monomers) to form a large molecule (polymer). Free-radical polymerization follows a mechanism with initiation, propagation, and termination steps.

Initiation Step (general form): $I_2\to 2I\cdot$ (where I₂ is the initiator, e.g., a peroxide)

Properties of Polymers: The physical properties of a polymer, such as density, flexibility, and strength, are determined by its molecular structure (e.g., branching, crystallinity). LDPE has a highly branched structure, resulting in a lower density and more flexibility compared to the linear HDPE.
