The species which has its fifth ionisation potential equal to 340v is
Dear Gaurav For the fifth ionisation potential we have to look that after removal of 4 electrons which species out of the given options will be a hydrogen like species i.e. having 1 electron. Thus (iii) B and (ii) C+ will be hydrogen like species after the removal of four electrons. Now among B and C+ we can find which will have ionisation potential = 340 V by using Bohr's equation.One eV is the energy acquired by the electron under a potential difference of 1 volt.1 eV= 1.602× 10-19 C × 1VoltThus 340 Volts will cause energy = 340eVFor the ionisation potential, E = E(infinity) - E(1)E = 13.6 z²/n² n = 1340 = 13.6 * z²/1²z² = 25z = 5 Since Z (atomic number ) = 5 corresponds to B . Thus B (Boron) will have fifth ionisation potential equal to 340 V. RegardsArun (askIITians forum expert)
