Homework Answers
1. Carbon has two single bonds with fluorine and one double bond with Oxygen. 3 sigma bond and one pi bond.
Hence the statement is false.
2.
Molecule has no lone pair in the central atom hence molecular and electron geometry is same.
geometry is trigonal planar.
so statement is true.
3.
Oxygen has two lone pairs of electrons . statement is true
4. Molecule has no symmetry hence polar.
5.
Hybridization of central atom (carbon) is sp2 . Hence statement is false.
