Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Option B is incorrect. H₄P₂O₆ (hypophosphoric acid) is tetrabasic, not tribasic, as it has four ionizable H atoms. It does contain a P-P linkage.

 

Explanation for other options:

A. Hyponitrous acid (HON=NOH) exhibits cis-trans isomerism.

C. CCl₄ and SiCl₄ have different molecular weights and thus different boiling points due to varying London dispersion forces.

D. B₂²⁺ has 10 electrons. Its molecular orbital configuration is ${\sigma }_{1s}^2{\sigma }_{1s}^{\ast 2}{\sigma }_{2s}^2{\sigma }_{2s}^{\ast 2}{\pi }_{2p}^0$

 

. Bond order is $(4-4)/2=0$

 

. It does not exist.
