Which structure is linear?
SO2
CO2
CO2-3
SO2-4
The BCI3 is a planar molecule whereas NCI3 i pyramidal because
B - CI bond is more polar than N-CI bond
N-CI bond is more covalent than B-CI bond
Nitrogen atom is smaller than boron atom
BCI3 has no lone pair but NCI3 has a lone pair of electrons
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
