This is a question from BR's Organic Chemistry, Section I Passage 1:
Alkene; Heats of hydrogenation (kcal/mole)
H2C=CH2 ; -32.6
RHC=CH2 ; -30.2
cis-RHC=CHR ; -28.5
R2C=CH2 ; -28.3
trans-RHC=CHR ; -27.4
R2C=CHR ; -26.7
R2C=CR2 ; -26.4
The greatest amount of energy is released by the oxidative cleavage of an alkene that is
A. Unsubstituted
B. Monosubstituted
C. Disubstituted
D. Trisubstituted
A. Everything's awesome and makes sense.
Next question:
The greatest amount of energy is required to break which of the following carbon carbon bonds?
A. H3C-CH3
B. (H3C)3-C(CH3)3
C. H2C=CH2
D. (H3C)2C=C(CH3)2
Answer is D. Not C. So confused...any insight?
