The c-c bond length in propene is little shorter (1.49 ∘A) then the c-c bond length (1.54 ∘A) is ethane. This is due to
+I effect of CH3 group
Mesomeric effect
Electronic effect
Hyperconjugation effect
On catalytic hydrogenation ethylene gives ethane. During this reaction
hybridization of carbon atoms changes from SP2 to SP3
bond angle decreases from 120 to 109.5
C-C Bond length increases from 1.34 A° to 1.54 A°
all of these
