Answer:
there are two types of nomenclature used in organic system. the most widely used and universally accepted system of nomenclature is the IUPAC system of nomenclature. some compounds are referred to by their common name that existed before the IUPAC system or is more widely known than the IUPAC names.
Explanation:
IUPAC ( international union of pure and applied chemistry) system of nomenclature is used to name compounds in organic system. there are some principles to be followed while using this nomenclature. some of them are:-
1) identification of parent chain is the first step. the longest hydrocarbon chain is the parent chain.
2) identification of all the substituent groups of the parent chain is also required.
3) hydrocarbon cyclic ring has a fixed prefix and that is cyclo.
A molecule has an empirical formula of ch, and its molar mass is known to be 26 g/mol and the molecular formula is C₂H₂ ethyne
Molecular formula of compound is (CH)n and the given molar mass is 26g/mol
Molar mass of (CH)n, C=12=n(12+1)=13n
So 13n and n=2
=13×2=26 and given molar mass is also 26g/mol
So here two carbon and two hydrogen so molecular formula is C₂H₂ and name is ethyne

<h2>Let us complete it :</h2>
Explanation:
let us study about formation of sodium phosphide
Electrons are transferred from atoms of sodium to atoms of phosphorous
The sodium atom looses electrons and the phosphorus atoms
gains electrons .
C. This transfer makes the sodium atoms acquire positive charge and phosphorous acquire negative charge .
As a result, the sodium and phosphorus atoms strongly bond with
each other.
Delta H = q / mass * delta temperature
Here is a picture of which shows you how many valence electrons are in the Lewis structure of xeo4
