The synthesized ILs were characterized with nuclear magnetic resonance spectroscopy (NMR) and elemental analyser (CHNS). Various thermophysical properties such as refractive index, density, viscosity and thermal stability were measured over wide temperature range. From the density experimental data, different volumetric properties were estimated using well established empirical equations. Moreover, the effect of temperature and increase of alkyl substitutions attached to anion has been evaluated for the studied properties. The toxicity of the synthesized ILs has been assessed against three human pathogenic bacteria i.e., Aeromonas hydrophila A97 (AH), Escherichia coli E149 (EC), and Staphylococcus aureus S244 (SA) in light to identify the influence of increasing alkyl substitution of the anion moiety on the overall toxicity of PILs. © 2017 date: 2018 publisher: Elsevier B.V. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85034435415&doi=10.1016%2fj.molliq.2017.10.141&partnerID=40&md5=872bac3d648b85e3b8ba9d1773c31e1f id_number: 10.1016/j.molliq.2017.10.141 full_text_status: none publication: Journal of Molecular Liquids volume: 249 pagerange: 583-590 refereed: TRUE issn: 01677322 citation: Khan, A.S. and Nasrullah, A. and Ullah, Z. and Bhat, A.H. and Ghanem, O.B. and Muhammad, N. and Rashid, M.U. and Man, Z.
