Name the following compounds:
a. CO
b. PCl₃
c. P₄Br₈
d. N₂S₆
e. H₂O
f. Si₉F₇
Answer (3)
The student is asking for the names of various chemical compounds, which requires an understanding of chemical nomenclature rules for both covalent and ionic compounds. Covalent compounds generally consist of two nonmetals bonded together, and their names are formed using prefixes to denote the number of atoms present. Ionic compounds are formed from a metal and a nonmetal, or from a metal and a polyatomic ion.
(a) CO is named carbon monoxide.
(b) PCl3 is named phosphorus trichloride.
(c) P4Br8 is named tetraphosphorus octabromide.
(d) N2S6 is named dinitrogen hexasulfide.
(e) H2O is named water, but sometimes referred to in a more scientific context as dihydrogen monoxide.
(f) Si9F7 does not follow traditional nomenclature rules and may likely be a typo or a non-standard compound; in typical nomenclature this compound does not exist and therefore cannot be named .
The name the following compounds can be noted as -
COb: This compound consists of one carbon atom and one oxygen atom, so it is named carbon monoxide.
PCl3: This compound contains one phosphorus atom and three chlorine atoms, so it is named phosphorus trichloride.
P4Br8: This compound comprises four phosphorus atoms and eight bromine atoms, thus it is named tetraphosphorus octabromide.
N2S6: With two nitrogen atoms and six sulfur atoms, this compound is named dinitrogen hexasulfide.
H2O: Known as water, this compound consists of two hydrogen atoms and one oxygen atom.
Si9F7: This compound includes nine silicon atoms and seven fluorine atoms, so it is named nonasilicon heptafluoride.
The compounds can be named as follows: CO is carbon monoxide, PCl₃ is phosphorus trichloride, P₄Br₈ is tetraphosphorus octabromide, N₂S₆ is dinitrogen hexasulfide, H₂O is water or dihydrogen monoxide, and Si₉F₇ can be named nonasilicon heptafluoride. These names follow standard chemical nomenclature rules. Understanding these rules is crucial for proper identification and communication in chemistry.
