Answer #1
  1. lewis acids are those species which can accept an lone pair of electron any lone pair done species
    NH3 IT HAVE NO VACCANT ORBITAL TO TAKE ELECTRONS FROM ANY DONAR HAVIN COMPLETE OCTATE
    F- IT HAVE ALSO NO VACCANT ORBITAL TO TAKE ELECTRONS FROM ANY DONAR HAVIN COMPLETE OCTATE
    H2O IT HAVE ALSO NO VACCANT ORBITAL TO TAKE ELECTRONS FROM ANY DONAR HAVIN COMPLETE OCTATE
    BF3- IT HAVE ALSO NO VACCANT ORBITAL TO TAKE ELECTRONS FROM ANY DONAR HAVIN COMPLETE OCTATE
    Zn2+ IT HAVE VACCANT d ORBITAL TO TAKE THE ELECTRONS SO CAN ACT AS LEWIS ACID
    SO Zn2+ CAN ACT AS LEWIS ACID

In what way does the Lewis structure of BF3 appear to violate the octet rule? A)BF3 can react with NH3 to form a compound with a B—N bond for which the nitrogen provides both of the electrons. B)Experimental measurements suggest that the B—F bonds are unexpectedly short. C)To adhere to the octet rule, the Lewis structure of BF3 would require a formal positive charge on one of the electronegative fluorine atoms. D)In the simple Lewis structure of BF3 there are...
