When the hybridisaiton state of carbon atom changes from sp3 to sp2 and finally to sp, the angle between the hybridised orbitals
Decreases gradually
Decreases considerably
Is not affected
Increases progressively
The boiling point of p-nitrophenol is higher than that of o-nitrophenol because
NO2 group at p-posiiton behave in a different way from that at o-position
