The relationship between the dissociation energy of N2 and is
dissociation energy of > dissociation energy of N2
dissociation energy of N2 = dissociation energy of
dissociation energy of N2 > dissociation energy of
dissociation energy of N2 can either be lower or higher than the dissociation energy of
Among the following orbital bonds, the angle is minimum between
sp3 bonds
px and py orbitals
H-O-H in water
sp bonds
The bonding point of p-nitrophenol is higher than that of o-nitrophenol because
NO2 group at p-position behave in a different way from that at o-position.
intramolecular hydrogen bonding exists in p-nitro phenol
there is intermolecular hydrogen bonding in p-nitrophenol
p-nitrophenol has a higher molecular weight than o-nitrophenol
