(i) Draw the structure of :
(a) BrF3
(b) XeOF4
(ii) Explain giving reason in each case :
(a) Why H2Te is more acidic than H2S ?
(b) Why are halogens strong oxidising agents ?
(c) Why does nitrogen show catenation tendency less than phosphorus ?
(i)
(ii) (a) Because of low bond dissociation enthalpy of H-Te bond.
(b) Because of their strong electron affinity, they easily accept an electron to complete their octet
(c) Because N-N single bond is weaker than P-P single bond.
