Question
A molecule has the formula C2H5OH. What is its atomicity?
Correct Answer
Option D is the correct answer.
Detailed Explanation
The formula C2H5OH contains 2 C atoms, 5 H atoms from the C2H5 group, 1 O atom, and 1 H atom from the OH group. Total C = 2, total H = 5 + 1 = 6, total O = 1. Total atoms = 2 + 6 + 1 = 9.
Hint
Write the condensed formula as C2H6O to count atoms more easily.
