Abstract:
The theoretical (Freebase, Cationic species) and experimental investigations on the molecular structural, spectroscopic characterization, and electronic properties of N2M5MB are reported. The most stable structure of the N2M5MB was analysed by employing Density Functional Theory (DFT) at different functional such as B3LYP, PBEPBE, TPSSTPSS and IEF-PCM (Freebase) and Cationic (B3LYP, IEF-PCM)/ 6-311++G (d,p) basis set level. The Potential Energy Scan (PES) analysis has been employed to investigate the conformational preference of the title molecule. The optimized molecular geometry, vibrational assignments (FT-IR, FT-Raman) of wavenumbers have been performed for freebase, cationic species (Gas, PCM) for the individual modes of vibration. The experimental UV-Vis absorption spectrum was obtained and compared with the simulated (Freebase, Cationic species) Time-Dependent (TD-DFT-M062X) method. The FMO's, electron-hole distributions, HOMA, FLU, Hirshfeld surface analysis, Electrostatic potential surface (ESP), Fukui functions, and topological parameters were discussed. Molecular docking studies were performed for the N2M5MB (ligand) into the active site of targeted proteins (1H22, 4DTL, 5OV9) which belong to AChE inhibitors with the minimum binding energy was detected.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the...
