A refinery laboratory is checking four proposed groups of alkanes.

Group	Molecular formulae of the alkanes in the group
J	$C5H12\text{C}_5\text{H}_{12}$ , $C6H14\text{C}_6\text{H}_{14}$ , $C7H16\text{C}_7\text{H}_{16}$
K	$C2H6\text{C}_2\text{H}_6$ , $C8H18\text{C}_8\text{H}_{18}$ , $C15H32\text{C}_{15}\text{H}_{32}$
L	$C4H10\text{C}_4\text{H}_{10}$ , $C11H24\text{C}_{11}\text{H}_{24}$ , $C19H40\text{C}_{19}\text{H}_{40}$
M	$C3H8\text{C}_3\text{H}_8$ , $C13H28\text{C}_{13}\text{H}_{28}$ , $C22H46\text{C}_{22}\text{H}_{46}$

Which group has the pattern expected for a single fraction of crude oil?
