Tricresyl phosphate is chemically represented as

ANS:A - (CH₃ C₆ H₄)₃ PO₄

Tricresyl phosphate (TCP) is an organophosphate compound commonly represented by the chemical formula (CH3C6H4)3PO4. Let's break down this formula:

1. (CH3C6H4): This part of the formula represents the tricresyl moiety. It consists of a methyl group (CH3) attached to a phenyl group (C6H4). The phenyl group, also known as the benzene ring, consists of six carbon atoms bonded together in a ring structure with alternating single and double bonds. The methyl group is a single carbon atom bonded to three hydrogen atoms.
2. 3: The subscript "3" indicates that there are three tricresyl groups in the molecule. This means that three tricresyl groups are attached to the phosphate group.
3. PO4: This part of the formula represents the phosphate group. It consists of one phosphorus atom (P) bonded to four oxygen atoms (O). The phosphate group is often found in organic compounds and plays various roles in biological systems and industrial applications.

Putting it all together, tricresyl phosphate (TCP) consists of three tricresyl groups attached to a central phosphate group, forming a triester compound. TCP is commonly used as a flame retardant, plasticizer, and lubricant additive. It's utilized in various industries, including the production of plastics, rubbers, and hydraulic fluids, as well as in aircraft hydraulic systems and as a flame retardant in textiles and furniture.
