A molecule XY, contains two σ, two π bonds and one lone pair of electrons in the valence shell of X. The arrangementof lone pair as well as bond pairs is57(a) Square pyramidal(b) Linear(c) Trigonal planar(d) Unpredictable

Answer»

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
