Question

In the disintegration series

The value of Z and A respectively will be

  1. 92, 236    
  2. 88, 230    
  3. 90, 234    
  4. 91, 234    

The correct answer is: 91, 234


    92 to the power of U to the power of 238 end exponent end exponent rightwards arrow subscript 2 end subscript H e to the power of 4 end exponent plus subscript 90 end subscript X to the power of 234 end exponent rightwards arrow subscript negative 1 end subscript e to the power of 0 end exponent plus subscript 91 end subscript U to the power of 234 end exponent
    Hence, A = 234, Z = 91

    In all the oxyacids of phosphorus, each phosphorus atom is in sp3 hybrid state, i.e., it is tetrahedrally bonded to neighbouring four atoms. All these acids contain P - OH bonds, the hydrogen atom of which are ionisable imparting acidic nature to the compound. The ous acids (oxidation state of P = +1 or +3) also have P - H bonds in which hydrogens are not ionisable (P and hydrogen have nearly same electronegativity). The presence of P - H group in these acids imparts reducing properties. The structure of the various acids are drawn below (note that the tetrahedral shape of phosphorus is not shown only for convenience of representation).

    There is very little difference in acid strength in the series H3PO4, H3PO3 and H3PO2 because
