Question

answer the questions in the table below about this molecule: what is this molecules chemical formula? note: write the simplest molecular chemical formula, in which each element symbol appears only once. how many ch₃, ch₂, and ch groups are in this molecule?

Explanation:

Step1: Count atoms

The molecule has 3 carbon (C) atoms, 8 hydrogen (H) atoms and 1 oxygen (O) atom.

Step2: Write chemical formula

The simplest molecular chemical formula is $C_{3}H_{8}O$.

Step3: Identify groups

There are 2 $CH_{3}$ groups and 1 $CH$ group, and 0 $CH_{2}$ groups.

Answer:

What is this molecule's chemical formula? $C_{3}H_{8}O$
How many $CH_{3}$, $CH_{2}$, and $CH$ groups are in this molecule? 2 $CH_{3}$, 0 $CH_{2}$, 1 $CH$
