- **668 cm⁻¹**: Out-of-plane C-H bending (aromatic); typical for disubstituted benzene derivatives. - **725 cm⁻¹**: C-Cl stretching (alkyl halide); strong and sharp, consistent with alkyl chloride vibrations. - **872 cm⁻¹**: C-H bending (aromatic); weak signal, indicative of specific substitution patterns in aromatic rings. - **1013 cm⁻¹**: C-O stretching (alcohols, ethers, or esters); broad and strong, characteristic of ether or ester functional groups. - **1102 cm⁻¹ & 1117 cm⁻¹**: C-O or C-N stretching; medium sharp peaks, common in ethers, esters, or amines. - **1163 cm⁻¹**: C-O or C-N stretching; medium broad, overlapping with ether/ester or amine vibrations. - **1266 cm⁻¹**: C-O or C-N stretching; strong broad peak, indicative of ester or amide functional groups. - **1388 cm⁻¹ & 1407 cm⁻¹**: C-H bending (alkanes); weak sharp peaks, typical of methyl or methylene groups. - **1455 cm⁻¹**: C-H bending (alkanes or aromatic); weak broad, associated with aliphatic chains or aromatic ring vibrations. - **1708 cm⁻¹**: C=O stretching (carbonyl); strong broad peak, characteristic of esters, ketones, or amides. - **2952 cm⁻¹**: C-H stretching (alkanes); weak broad, indicative of aliphatic chains.
**Conclusion:** The FTIR spectrum suggests the presence of an aromatic compound with a carbonyl group (C=O at 1708 cm⁻¹) and ether/ester functionalities (C-O stretches at 1013 cm⁻¹, 1102 cm⁻¹, 1117 cm⁻¹, and 1266 cm⁻¹). The strong C-Cl signal at 725 cm⁻¹ indicates an alkyl chloride substituent. The data collectively point to an aromatic ester or ketone with alkyl halide substitution.
