Isomers are compounds that have the same number and kinds of atoms but have a different arrangement of the atoms. The enthalpies of atom combination for several pairs of gaseos isomers are given here. For each pair, decide which has the strongest bonds.

a. CH3CH2CH2OH -4391.2kJ/molrxn
or CH3CHOH -4410.7 kJ/molrxn
|
CH3

b. CH2=CHCH2CH3 -4604.9 kJ/molrxn
or CH3CH=CHCH3 -4611.9 kJ/molrxn

c. H2C=CHCH=CHCH3 -5243.3 kJ/molrxn
or H2C=CHCH2CH=CH2 -5213.5 kJ/molrxn

How would I go about this problem?

The CH3 in a is supposed to be under the second C in the compound.
