Question

what is the condensed formula for the molecule shown below?

Explanation:

Step1: Identify carbon - hydrogen groups

In a condensed formula, we group the hydrogen atoms with the carbon atoms they are attached to. The left - most carbon has 3 hydrogens, the central carbon has 2 hydrogens, and the right - most carbon has 3 hydrogens.

Step2: Write the condensed formula

The structure is a 3 - carbon alkane. The central carbon is bonded to two methyl ($CH_3$) groups and one $CH_2$ group. The condensed formula is $(CH_3)_2CH_2$.

Answer:

$(CH_3)_2CH_2$
