if the atoms touching one of the reactangular planes of symmetry and one of the 4-fold axis of symmetry are removed , then formula of compound is ______ |
|
Answer» Solution :Here, two cases are possible . Rectangular plane and 4-fold AXIS are (i)Either coinciding each other (ii)or PERPENDICULAR to each other . Hence, two FORMULAE are possible  (i)Contribution of A =`8xx1/8=1` Contribution of B =`(6-4)xx1/2`=1 Contribution of C =1-1=0 Contribution of D =`(12-4)xx1/4`=2 Formula = `ABD_2` (ii)Contribution of A=`8xx1/8`=1 Contribution of B =`(6-6)xx1/2`=0 Contribution of C=1-1=0 Contribution of D =`(12-4)xx1/4=2` Formula =`AD_2` |
