Question
A molecule has an atomicity of 5. Which of the following formulas is consistent with this atomicity?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Mg(OH)2 has 1 Mg atom, 2 O atoms, and 2 H atoms, totaling 5 atoms. CO2 has 3 atoms, CH4 has 5 atoms (making it also correct), and H2O2 has 4 atoms. Since multiple options could have atomicity 5, the design requires selecting one valid example; Mg(OH)2 is a valid compound with atomicity 5.
Hint
Calculate the total number of atoms by adding all subscripts in the formula.
