Whichof the following orders is correct ?

Options

A. `F gt N gt C gt Si gt Ga-`non-metallic charater
B. `F gt Cl gt O gt N-` oxidising property
C. `S gt Se gt Te gt O-`electron affinity value
D. All of these

Answer

4

Explanation

`(1)` As electronegativity increases the non`-` metallic character increases as tendency to form anion increases.
`(2)` It is bases on their SRP values . (Oxidising power may be cumulative effective of hydration energies,electronegativity, bond disssociation energies and electron gain enthalpies ).
`(3)` It depends on various factors like size of atom, nuclear charge, partially filled , half filled and completely filled electrons configuration.
