Numbering off the longest carbon chain, we have a total of two carbons in this carbon chain. Since none of the carbons have double bonds or triple bonds with other carbons, the name of the longest chain will be "ethane". Moving on to label our side groups, we have three total chlorines attached to the carbon chain. 2 of the chlorine atoms are on the first carbon. 1 chlorine atom is on the second carbon. Thus, the name of this compound is " 1,1,2-trichloroethane ".
