Question
1-what is the electron geometry (or electron arrangements) around an atomic or ion which is surrounded by three lone pairs of electrons and one single bond.
a-tetrahedral
b- tringonal pyramidy
c- trigonal planer
d-bent
e-linear
2-which of the following statements is true?
a- a pi bond is twice as strong as a single bond
b- a pi bond results from the sideways overlap of hybridize orbital
c- a double bind consists of a pi bond and a bond
d- a pi bond has cylindrical symmetry about the bonding axis
e- a pi bond is twice as strong as a bond
Explanation / Answer
1)According to the valence-shell electron-pair repulsion (VSEPR) theory, when atom is surrounded by 3 lone pairs of electrons they repel each other and forms trigonal planer
2) option C is true.
a double bond consist of a pi bond and a single bond
