2. A lecithin molecule is a phosphoglyceride with choline as the alcohol group. Given the structure of chome below, use lauric acid and stearic acid to write a structure of a lecithin. Сн, HO-CH2CH2N -CHE CH Choline 3. Beeswax is a wax created by bees when they make their honeycomb. 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

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.
Based on the Lewis structure and your knowledge of VSEPR theory,
approximate the smallest bond angle in this molecule.
