“…A high value of fk + shows that the k atom has an electrophilic character indicating a high probability for a nucleophilic attack on that site where the high value of fkmeans that the k site is more nucleophilic and available for the electrophilic attacks 50,51 . The calculated Fukui indices for the CBIPM molecule are shown in Table 7.…”

The 2(-4(chloro phenyl-1H-benzo[d]imidazol)-1-yl)phenyl)methanone (CBIPM) was synthesized and tested as a corrosion inhibitor for mild steel in 1.0 M HCl solution using electrochemical and spectroscopy measurements. Results obtained showed that this compound has a good inhibition properties for mild steel corrosion in acidic medium which its inhibition efficiency value reaches 98.9 % at 10-3 M. So, the potentiodynamic polarization curves showed that the CBIPM has a mixed type inhibitor. In addition, it is shown that the obtained results were confirmed by the UV-vis spectroscopic measurements. It is found that the inhibitor forms a complex with Fe 2+ ion. On the other hand, the experimental results were completed by quantum chemical calculations using DFT method at the B3LYP/6-31G* level of theory. It is found that the theoretical and experimental results are in good agreement.

A new Azomethine derivative namely 5-(((4-hydroxybenzylidene)amino)methyl)quinolin-8-ol (HBHQ) was synthesized and identified by different spectroscopic methods. The product was assessed in the inhibition of corrosion of carbon steel (CS) in 1 M HCl using Tafel polarization, weight loss and electrochemical impedance spectroscopy. Their property anticorrosion is relative in concentrations and achieved 92% at the optimum concentration of 10-3 M. Polarization studies showed that that the newly synthesized inhibitor was of mixed type in nature. The EIS data bring that, the development of a protective layer of azomethine derivative increase the charge transfer resistance and decreases in the double layer capacitance of carbon steel in acid medium. The adsorption process at interface of carbon steel in hydrochloric acid by HBHQ was studied at different temperatures (298-338 K) by means of Tafel polarisation measurements. The adsorption of azomethine derivative on the carbon steel (CS) surface followed Langmuir adsorption isotherm and in order to discover the mode of adsorption process, various thermodynamic and activation parameters were evaluated. Quantum chemical calculations were performed using methods based on density functional theory (DFT/B3LYP) and Monte Carlo simulations (MCs). Indeed, the results obtained by this computation reflect a good agreement with the practical part.
