| Structural Formula | One carbon atom bonded with four hydrogen atoms | A straight chain with three carbon atoms. The carbon atoms at the two ends of the chain bond with three hydrogen atoms each. The carbon atom in the center bonds with two hydrogen atoms. | A straight chain with five carbon atoms. The carbon atoms at the two ends of the chain form single bonds with three hydrogen atoms each. The three carbon atoms in the center bond with two hydrogen atoms each. | A straight chain with eight carbon atoms. The carbon atoms at the two ends of the chain form single bonds with three hydrogen atoms each. The remaining six carbon atoms bond with two hydrogen atoms each. |
