The influence of cation–π and anion–π interactions on some NMR data of s-triazine…HF hydrogen bonding: A theoretical study

Removal of chlorpyrifos from waste water by wheat straw-derived biochar synthesized through oxygen-limited method

“…For a better understanding of the experimental observation, the charge in surface of WS750 at different pH was also investigated. 26,27 So, it is easy to explain why WS750 with a positive surface has a stronger adsorption for chlorpyrifos than that with negative surface. Based on Fig.…”

“…19 In most cases, the cation is most likely to interact with aromatic ring than anion. 26,27 So, it is easy to explain why WS750 with a positive surface has a stronger adsorption for chlorpyrifos than that with negative surface. In addition, there are O atoms in chlorpyrifos.…”

Preponderant adsorption for chlorpyrifos over atrazine by wheat straw-derived biochar: experimental and theoretical studies

“…21 Usually, more negative species has weaker interaction with aromatic ring than the less negative species since aromatic ring acts as electron donor in most of case. [35][36][37] In addition, these N atoms of atrazine can be protonated in acidic condition. This leads to that atrazine is positive in acidic condition and is neutral in basic condition.…”

The influence of carbon hybridization on coupling constants across C X⋯Cl F dihalogen bond: A computational study

“…1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 5 and also, increase in d Cl−F . For each carbon hybridization type, the Br-substituted system forms the strongest halogen bonded complex, followed in order by Cl and F. Similar to hydrogen bonded systems [45], the combination of d Cl−F and d X•••Cl can be very useful for studying dihalogen bonding phenomena:…”
