Naming H2S and Related Concepts

The video tutorial explains how to name the compound H2S as hydrosulfuric acid. It uses a flow chart to guide the naming process, starting with the prefix 'hydro', followed by the stem 'sulfur', and ending with 'ic acid'. An exception is noted for sulfur, where 'ur' is retained in the name. The final name is confirmed as hydrosulfuric acid.

What is the first step in naming the compound H2S?

• Write the element symbol

• Use the flow chart

• Add 'ic' to the stem

• Write 'hydro'

What is the role of the flow chart in naming H2S?

• To calculate the molecular weight

• To determine the chemical formula

• To identify the elements involved

• To guide the naming process

Which part of the word 'sulfur' is retained when naming H2S?

• The 'sul' part

• The 'fur' part

• The 'ur' part

• The 'ic' part

What is the correct name for H2S?

• Hydrosulfic acid

• Sulfic acid

• Hydrosulfuric acid

• Sulfuric acid

Why is sulfur an exception in the naming process?

• Because 'ur' is retained in the name

• Because it forms a diatomic molecule

• Because it is a non-metal

• Because it reacts with hydrogen
