Molecular geometry intermolecular attraction

Synthetic fibers are generally made from polymers whose chemical composition and geometry enhance intermolecular attractive forces and crystallization. A certain degree of moisture affinity is also desirable for wearer comfort in textile applications. The same chemical species can be used as a plastic, without fiber-like axial orientation. Thus most fiber forming polymers can also be used as plastics, with adjustment of molecular size if necessary to optimize properties for particular fabrication conditions and end u.ses. Not all plastics can form practical fibers, however, because the intermolecular forces or... 

Acetone, (CH3)2CO, is widely used as an industrial solvent. (a) Ehraw the Lewis structure for the acetone molecule, and predict the geometry around each carbon atom, (b) Is the acetone molecule polar or nonpolar (c) What kinds of intermolecular attractive forces exist between acetone molecules (d) 1-Piopanol, CH3CH2CH2OH, has a molecular weight that is very similar to that of acetone, yet acetone boils at 56.5°C and 1-propanol boils at 97.2°C. Explain the difference. 

The origin of attractive intermolecular interactions and the factors determining the geometry of molecular complexes is still being sought after decades of numerous experimental and theoretical techniques. The interaction energy, AE, is the difference between the energy of the species AB and the two isolated molecules A and...
