Question

1. what is the correct iupac name for the compound with the formula h₂o?

options:
dihydrogen monoxide
hydrogen oxide
hydrogen dioxide
water
clear all

Explanation:

To determine the correct IUPAC name for \( H_2O \), we analyze the options:

• "dihydrogen monoxide" is a non - traditional, often humorous name for \( H_2O \) based on the prefixes (di - for 2 H, mono - for 1 O) in the IUPAC naming of binary molecular compounds.
• "hydrogen oxide" is incorrect as it does not account for the number of hydrogen atoms.
• "hydrogen dioxide" would correspond to a formula like \( HO_2 \), not \( H_2O \).
• "water" is the common name of \( H_2O \), and the IUPAC - recognized systematic name for \( H_2O \) (when using the prefix - based naming for binary molecular compounds) is dihydrogen monoxide.

Answer:

A. dihydrogen monoxide
