is XeF2 polar? my package says its polar

i think its not. bcoz it has 2 LPs in equatorial positions whose dpms cancel each other & the two polar BPs also cancel out. this correct rite?

again

also is 1,4-dinitrobenzene polar?again my package says its polar..but ithink its not..coz the C-N dpms cancel out each other.. am i missing out any point over here?

hybridisation of XeF₂ is sp³ d . it has 3 lone pairs which are arranged in the equatorial position and 2 F on the axial position
it should be non polar according to me

Hybridisation of XeF₂ is sp³d whose structure is trigonal bipyramidal. In which the 3 lone pairs are present in equatorial position and the 2 flourine atoms are present in axial position. It doesnt mean that it is non polar. Rather it is polar bcz of the three lone pairs...

yes it is.

bonding in this involves 5pz of xe and 2pz orbital of the 2 f atoms . these three orbital combine to give three molecular orbital, one bonding , one nonbonding and one antibonding. thus 2 electron occupy the bonding molecular orbital and this pair of electron is responsible for binding all the three atoms . the remaining 2 electron goes to the nonbonding MO which is situated mainly on f and confer to ionic character
