  • Effect of Pyridine Type Nitrogen (=N-) on Hammett : Invoking the
           Reactivity-Selectivity Principle: A Chemical Education Perspective

    • Authors: R. Sanjeev; V. Jagannadham
      Pages: 91 - 94
      Abstract: Hammett ρ values are estimated for the two acid dissociation equilibriums eqn. 1 and 2 of pyridinium and pyridazenium ions from the Hammett plots of log KaH versus Hammett σ values. The Hammett ρ values are found to be 5.94 and 5.29 for the two equilibriums eqns. 1 and 2 respectively. The effect of extra pyridine type nitrogen (=N-) on Hammett ρ is discussed. Similarly, the average lone pair ionization potentials (IP) of pyridines and pyridazines also followed Hammett equation with Hammett ρ of 1.18 for pyridines and 0.38 for pyridazines respectively. This article is useful in an undergraduate and graduate classroom who tries to study the substituent effects and reactivity-selectivity principle.

  • Optimization of Detergent Pre-formulations Using Machine Learning
           Techniques

    • Authors: Ketan Jangir; Abhisek Gour, Naveen Kumar Suniya, Santosh Kumari Meena, Naginder Singh, Kapil Parihar, Umesh Kumar
      Pages: 95 - 102
      Abstract: Detergents play an essential role in several industrial and domestic applications in modern society. Much research is carried out to identify the right combination of surfactants and stabilizers to optimize the detergent formulations. In recent times, machine learning techniques have been used extensively to model problems where the input-output relationship between process parameters has to be studied. In this research, a detergent pre-formulation has been designed using an aqueous solution of Tween-20, Ethanol & 1-Octanol. To determine the optimal values of the ingredients of the formulations, supervised machine learning models were developed and optimized for the Ross Miles Index 30ml (RMI 30) and cleaning time (CT). Three regression models based on linear, 2FI and Quadratic designs were developed. ANOVA analysis of trained models reported an optimal p-value of 0.0018 for RMI 30 and less than 0.0001 for CT. The proposed optimal mixture was validated by creating the pre-formulation and testing it for RMI 30 and CT.

  • pKaH of the Two Conjugate Acids (CH2N5+) and (HN6+) of Two Hypothetical
           Molecules the Pentazine (CHN5) and the Hexazine (N6) of Azabenzene Series:
           A Chemical Education Perspective

    • Authors: R. Sanjeev; R. Ravi, D. A. Padmavathi, V. Jagannadham
      Pages: 105 - 109
      Abstract: Extrapolation of a simple straight-line graph is used to calculate the pKaH of two cations (CH2N5+) and (HN6+) (eqn. 1 and 2) of two hypothetical molecules pentazine (CHN5) and hexazine (N6). This is achieved by simply an extrapolation of the locus of the plot of pKaH of protonated pyridine, pyridazines, s-triazine and 1,2,4,5-tetrazine versus the number of nitrogen atoms of the cyclic azines. Even well matched pKaH values for these two species were found from the extrapolation of the locus of the plot of pKaH versus average ionization potential (Iv/eV) of the neutral azines. This article is useful in graduate research classroom to explain the acid-base properties and to determine the pKaH values.

  • Greening Qualitative Organic Analysis: Spot Test to Detect Aromatic
           Hydrocarbons and Aryl Halides

    • Authors: Sujata Sengupta; Sharda Mahilkar Sonkar, Shivani Singh, Ankita Duggal, Mamta Siwach
      Pages: 110 - 113
      Abstract: Chemistry students in their college laboratory routinely employ qualitative reactivity patterns to identify functional groups of unknown organic compounds. Qualitative organic analysis is therefore very useful for determining the overall structure. Most of the common functional groups can be easily detected by simple color tests that are rapid, simple and routinely performed by the students. However, the detection of aromatic hydrocarbons and aryl halides is still a challenge as there are not many color tests available. The present work highlights the detection of aromatic hydrocarbons and aryl halides by simple modification of their reaction with chloroform. The method is simple, using chemicals that are easily available in the undergraduate laboratory and follows the principles of green chemistry.
