Verified Answer
Direction (Q. Nos. 18) Choice the correct combination of elements and ...
∆H = ∑(B.E)reactant - ∑(B.E)product
For CH4
C(g) + 4H(g) → CH4
∆H = (718.4) + 4(217.95) - (-74.9)
4 C-H  = 1665.1
C-H = 416.3
For C2H6
2C(g) + 6H(g) → C2H6(g)
∆H = 2(718.4) + 6(217.95) - (-84.7)
C-C+ 6C-H = 2828.5
C-C = (2828.5 - 2497.8) = 331.4 
From here, we can see that option c is correct.
