Cyclic hydrocarbon ′A′ has all the carbon and hydrogen atoms in a single plane. All the carbon carbon bonds have the same length, less than 1.54A∘, but more than 1.34A∘. The bond angle will be
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
Why in ethene angle between carbon hydrogen bonds is slightly less than angle between carbon hydrogen and carbon carbon Bond?
