Question

Which of the following is zerone?
A) ${\text{C}}{{\text{H}}_{\text{3}}}{\text{CHO}}$
B) ${\text{C}}{{\text{H}}_{\text{3}}}{\text{OH}}$
C) ${\text{C}}{{\text{H}}_{\text{4}}}$
D) ${{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}{\text{OH}}$

Answer 1

The full form of IUPAC is the International Union of Pure and Applied Chemistry. It is a World Wide organisation for the nomenclature of the new elements in the periodic table and chemical molecules. We have to know that the IUPAC has certain rules and regulations for the naming of the organic compound. In that method only we named the organic molecules in World level. The naming of any organic molecule depends on the parent saturated hydrocarbon.

Complete answer:
The IUPAC name of ${\text{C}}{{\text{H}}_{\text{3}}}{\text{CHO}}$ is ethanal.
The IUPAC name of ${\text{C}}{{\text{H}}_{\text{3}}}{\text{OH}}$ is methanol.
The IUPAC name of ${\text{C}}{{\text{H}}_{\text{4}}}$ is Methane.
The IUPAC name of ${{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}{\text{OH}}$ is ethanol.
Methanol is considered as zerone.
According to the above discussion, we conclude Methanol is zerone.
Hence, option A not is correct, because ethanal is not a zerone.
Option B is correct, because Methanol is zerone.
Option C not is correct, because Methane is not a zerone.
Option D not is correct, because ethanol is not a zerone.

Note:
As we know that the functional group of the molecule is very important for the naming time. If one molecule having more than one functional group means some priority list is also provided from IUPAC. If the number of substituent and functional group is dependent on the minimum number will come from the left side or right of the terminal carbon atom in the chain. The aldehyde functional group in the molecule ends with al. it is one of the IUPAC rules for the naming of functional groups.
