Answer:
3,4-dimethylhexane, CH3CH2CH(OH)CH3, CH3CH2CH(CH3)CH2CH2CH3
Step-by-step explanation:
A chiral carbon atom is also referred to as a asymmetric carbon atom. This is a carbon atom that is bonded to four different substituents.
So what we need to do is to look at each compound and consider all the carbon atoms in each compound. Drawing out the full structural formula is very helpful here.
After drawing each structure out, we now look out for carbon atoms that have four dissimilar substituents. Those are the chiral carbons. If we do so for all the molecules listed in the answer, we will discover that each of them contains an asymmetric carbon atom.
