Name the following binary compounds consisting of two nonmetals or a metalloid and a nonmetal.
1. AsH3= arsine
2. AsF5= arsenic pentafluoride
3. HCL= Hydrogen chloride
is this right?
arsenic trihydride, or in the stock system Arsenic(III)hydride
yes on 2, in stock system, arsenic(V)fluoride
yes, correct, if the HCl is dissolved in water, it is hydrochloric acid.
Here are the correct names for the binary compounds you mentioned:
1. AsH3 = Arsenic trihydride (also known as arsine)
2. AsF5 = Arsenic pentafluoride
3. HCl = Hydrogen chloride
So, you got the names of compounds 1 and 2 correct, but the name for compound 3 should be "Hydrogen chloride" instead of "HCL."
Yes, your answers are correct! Here's an explanation of how to name each compound:
1. AsH3: To name this compound, you need to know the names of the individual elements. As is the chemical symbol for arsenic, and H is the symbol for hydrogen. The prefix "ars-" is added to the ending "-ine" to form "arsine." So, AsH3 is named "arsine."
2. AsF5: Similarly, we have the chemical symbol As for arsenic and F for fluorine. Since we have five fluorine atoms, we use the prefix "penta-" to indicate this. So, AsF5 is named "arsenic pentafluoride."
3. HCl: In this case, H stands for hydrogen, and Cl represents chlorine. When a binary compound is formed between a nonmetal and a nonmetal, the ending "-ide" is used for the second element's name. Therefore, HCl is named "hydrogen chloride."
Remember that the naming conventions for binary compounds involving nonmetals or metalloids and nonmetals follow specific rules, which involve knowing the chemical symbols of the elements and the appropriate prefixes or suffixes.
