Question

Carbinol is a trivial name of:
(A) $C_2{H}_{5}OH$
(B) $C{H}_{3}OH$
(C) $HCOOH$
(D) $C{H}_{3}COOH$

Answer 1

Hint: Every chemical compound has a chemical name or IUPAC name. Such a name helps in understanding the structure and properties of the compound. But some compounds are so much in use that they are usually called by their common name rather than chemical name. Such a common name of a compound is called a trivial name.

Complete Step by step answer:Lets start one by one considering each question.
(A) $C_2{H}_{5}OH:$ Ethanol is an Organic chemical compound. It is a simple alcohol with the chemical formula $$C_2{H}_{5}OH.$$ Its formula can be written as $C{H}_3-C{H}_2-OH$ or $C_2{H}_{5}OH$ and is often abbreviated as ethanol $OH.$ Ethanol is a volatile, flammable, colorless liquid with a slight characteristic order.
(B) $C{H}_{3}OH:$ Methanol, also known as methyl alcohol amongst other names, is a chemical with the formula $C{H}_{3}OH.$ It is a light, volatile colorless, flammable liquid with a distinctive alcoholic order similar to that of ethanol. Methyl alcohol is commonly known as methanol or carbinol.
(C) $HCOOH:$ Formic acid, systematically named methanoic acid, is the simplest carboxylic acid and has the chemical formula $HCOOH.$ It is an important intermediate in chemical synthesis and occurs naturally, mass notably in the same ants.
(D) $C{H}_{3}COOH:$ Acetic acid $(C{H}_{3}COOH)$ also called ethanoic acid the most important of the carboxylic acid. A dilute solution of acetic acid produced by fermentation and oxidation of natural carbohydrates is called vinegar, a salt, ester or acyl of acetic acid is called acetate.

Therefore, from the above explanation the correct option is (B) $C{H}_{3}OH.$

Note: There are some compounds who are famous by their common names. You can solve such questions only if you know their common names. There is no other way to figure out which option would be correct as the common names do not have any characteristic property to explain the structure or formula of the compound like IUPAC names do. Carbinol is also called wood alcohol because it can be made by distillation of wood.
