Question

Fill in the blanks with appropriate words:
$\left( a \right)$ Synthetic fibres are also called ______ or ______ fibres.
$\left( b \right)$ Synthetic fibres are synthesised from raw material called ______.
$\left( c \right)$ Like synthetic fibres, plastic is also a _______.

Answer 1

Hint:The polymerisation process takes place from raw materials available naturally, which is why organic molecules are produced for specific purposes. The process of binding of the monomeric units occurs in the presence of high pressure and at high temperature.

Complete answer:
$\left( a \right)$ The synthetic fibres are also known as man-made fibres or artificially created fibres which can be prepared from specific raw materials. They are considered man-made fibres as they do not exist in nature or cannot be formed by natural means. There are specific processes in which raw materials are converted to the synthetic fibres which are later used for various purposes among the items for daily usage.
$\left( b \right)$ The raw materials which are used in the process of production of synthetic fibres are known as petrochemicals. The fossil fuels which are extracted from below the earth’s crust are subjected to treatment so that the fuel components can be separated from the fuel. These chemical elements are organic components when separated have different chemical properties. Hence their uses are separate as well. These raw materials are used for the process of formation of the synthetic fibres to be produced which are mainly formed through polymerisation of the components. This is the importance of by-products of petroleum as the chemicals together form the synthetic fibres.
$\left( c \right)$ Just like synthetic fibres, the plastic is also a polymeric structure. The plastic is mainly polyethene which is a polymeric structure of the molecule ethylene. This polyethene structure is the original structure of the plastic and this polymeric nature is similar to that of the synthetic fibres as these fibres are also polymeric.

Note:
The biopolymers can be produced artificially as not all molecules which are formed from organic molecules are produced naturally. Some of the molecules are prepared through specific processes of chemical synthesis of biomolecules.
