A. IUPAC name of ethylene glycol is ethane -1, 2 - diol. It is primarily used as raw material in the manufacturing of polyester fibers and fabric industry. A small percentage of it is used in antifreeze formulations.
B. Ethanol is a good solvent for fatty and waxy substances Fats and waxes provide odour to the perfumes. Apart from being a good solvent, it is less irritating to the skin. So, it is used in perfumes
C. Phenol is converted into picric acid (2, 4, 6-trinitro-phenol) by the reaction of phenol with conc. $H N O_{3}$

D. Methanol, $C H_{3} O H$ is also known as 'wood spirit' as it was produced by the destructive distillation of wood.
E. Neutral ferric chloride gives purple/red colour when treated with phenols. It is the reagent used for detection of a phenolic group.
F. Soaps are prepared by the reactions of fatty acid with NaOH.

This glycerol (propan -1, 2, 3 - triol) is the by-product of the soap industry and used in cosmetics.
