Q1: Tricresyl phosphate is chemically represented as

ANS:A - (CH₃ C₆ H₄)₃ PO₄

Apologies for the formatting confusion. Let's break down the chemical formula (𝐶𝐻3𝐶6𝐻4)3𝑃𝑂4(CH3​C6​H4​)3​PO4​ step by step:

1. 𝐶𝐻3CH3​ represents a methyl group, which consists of one carbon atom (C) bonded to three hydrogen atoms (H).
2. 𝐶6𝐻4C6​H4​ represents a phenyl group, which is a six-membered ring of carbon atoms with alternating single and double bonds, commonly referred to as benzene. This formula represents a benzene ring, where each carbon atom is bonded to one hydrogen atom.
3. (𝐶𝐻3𝐶6𝐻4)3(CH3​C6​H4​)3​ indicates that three of these combined methyl and phenyl groups are present. So, (𝐶𝐻3𝐶6𝐻4)3(CH3​C6​H4​)3​ essentially represents three groups of a methyl group attached to a phenyl group.
4. 𝑃𝑂4PO4​ represents a phosphate group, consisting of one phosphorus atom (P) bonded to four oxygen atoms (O).

Putting it all together, (𝐶𝐻3𝐶6𝐻4)3𝑃𝑂4(CH3​C6​H4​)3​PO4​ signifies a molecule where three groups consisting of a methyl group attached to a phenyl group are bonded to a phosphate group. Tricresyl phosphate is an example of such a compound, commonly used as a plasticizer and flame retardant in various industrial applications.
