Figure 3From: Study of liquid-phase molecular packing interactions and morphology of fatty acid methyl esters (biodiesel) Proposed configuration for the ester groups of two opposite MO molecules interacting with each other. The resonance structures of the ester group result in weak interactions between the polarized hydrogen of the methyl carbon and the oxygen of the carbonyl on the opposite MO molecule. This molecular arrangement for MO would maximize the polar interactions.Back to article page
