N2and O2, are converted into monoanions N-2 and O-2 respectively. Which of the following statements is wrong?
In N2, the N-N bond weakens
In O-2, O-O bond length increase
In O-2, bond order decreases
N-2, becomes diamagnetic
In which of the following molecules, the central atom said to adopt sp2-hybridisation?
BeF2
BF3
C2H2
NH3
H2O has a net dipole moment while BeF2 has zero dipole moment because.
H2O molecules is linear while BeF2 is bent
BeF2 molecule is linear while H2O is bent
Fluorine has more electronegativity than oxygen
Beryllium has more electronegativity than oxygen
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
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
The correct order of the O-O bond length in O2, H2O2 and O3 is
