state whether the following are correct or incorrect

1)sp² hybridised orbitals bonded to same substitunts have equal s and p character

2)hybridised orbitals always form σ bonds(if incorrect then plz give example where hybridised orbitals forms bond rather than σ bond)

i need explanation

1) false...

s char=        (no of s orbitals)    = 33% for sp2

                 total no of orbitals

2)   true   

hybridised orbitals are very directional.. ie they they have a fixed direction

and for an atom, hybrid orbitals are symmetrically  spaced out..

to form a pi bond 2  HOs  would need to come together.. this is very difficult for them as they cant leav their position.. so no double bonds...
