Verified step by step guidance

Identify the skeletal formula provided in the image. The skeletal formula shows a central carbon atom bonded to an OH group and two other carbon atoms.

Translate the skeletal formula into a condensed formula. The central carbon atom is bonded to an OH group, and the two other carbon atoms are each bonded to three hydrogen atoms. This gives the condensed formula CH3CH(OH)CH3.

Convert the condensed formula into a structural formula. The structural formula will show each atom and its bonds explicitly. Start with the central carbon atom bonded to the OH group, then add the two CH3 groups on either side.

Ensure that the structural formula accurately represents the connectivity of the atoms. The central carbon should be bonded to the OH group and two CH3 groups, each with three hydrogen atoms.

Review the structural formula to confirm that it matches the condensed formula CH3CH(OH)CH3, ensuring that all atoms and bonds are correctly represented.
