Is the following an ionic compound, polar molecule or nonpolar molecule? charged group of CCR5 residue Tys3 through hydrogen bond interactions between the backbone amide of Ile30 and Tys3 OS(2-4). The more electronegative atom has a partial negative charge, d -, because the electrons spend more time closer to that atom, while the less electronegative atom has a partial positive charge, d +, because the electrons are partly (but not completely) pulled away from that atom. Difference in electronegativity of the two atoms is 0 therefore the covalent bond between them is non-polar. Rhodanine derivatives of merocyanine dyes with residues of 1,3,3-trimethyl-3H-indole and 3-ethylbenzothiazoline have been found to possess two molecular forms in diluted solutions of polar solvents such as dimethylformamide, dimethyl sulfoxide, and N-methylpyrrolidinone.
