Its major component is triacontanyl palmitate which is an ester of the alcohol triacontanol, HO-CH2)29CH), and palmitic acid. Using line-angle formulas draw the structure of beeswax. 4. Progesterone, a steroid...
A Lewis structure is a two-dimensional representation of a molecule that does not necessarily show what shape that molecule would take in three dimensions. From the given Lewis structure and what you know about VSEPR theory, identify the shape of the molecule. O bent see-saw O T-shaped 0 square planar O octahedral trigonal planar trigonal pyramidal tetrahedral linear trigonal bipyramidal O square pyramidal
