Question

The vapour pressure of an aquous solution of cane sugar is 75.6 cm of Hg at100 degree centigrade what is the molality of the solution

Answer 1

All the four species are isoelectronic. They contain same number of electrons (14 electrons) . Hence, they are isostructural and have identical bond order. In these species, all the electrons are paired. Hence, they are diamagnetic. Due to presence of resonance structures, more than one species have zero dipole moment. Hence, all the four statements are true.
