in my view it shd be a trigonal planar structure

Its structure may be as


       y- x = y

we does not consider lone pair for geometrical structure

hence structure will be as y-x

geometry should be linear

according to me, since there are three sigma bond equivalents therefore hybridisation should be sp2(lone pair=1 sigma bond equivalent, and two sigma bonds).so structure should be trigonal planar but bond angle will be a little contracted due to lone pair and bond pair repulsions.SmileSmile

Pi bond is stay along with sigma bond ...therefore the total number of valence electron of X is equal to 8 .possible structure is Y-Xtripple bond Y..structure is linear
