1.	Account for the following/Explain why :(1) Interhalogens are more reactive than halogens.(2) N2 is less reactive at room temperature.(3) Reducing character increases from NH3 to BiH3.
Answer» (1) Interhalogens are more reactive than halogens (except F) because A–X bonds in dihalogen interhalogens are weaker than the X–X bonds in dihalogen molecules. (2) Because dinitrogen is formed by sharing three electron pairs between two nitrogen atoms resulting into the triple bond. As a result the bond dissociation energy is quite high causing N₂ to be less reactive. (3) The reducing character depends upon the stability of the hydride. Since BiH₃ is the least stable (least electronegative) than other elements in the group, therefore they can easily donate electron pair. Therefore, reducing character increases from NH₃ to BiH₃.
