Question

List the following information for: CF2H2, HCN, HCOCl, HOCl 1) # of valence electrons 2) Central atom 3) VSPER electron groups on central atom 4. # bonding groups on central atom 5. molecular geometry 6. polar or non-polar

Answer 1

	Number of valence electrons	Central atom	VSEPR electron groups on central atom	#bonding groups on central atom	Molecular geometry	polar or non-polar
CF2H2	4	C	4	4	TETRAHEDRAL	Polar
HCN	4	C	2	2	Linear	Polar
HCOCl	4	C	3	3	Trigonal planar	Polar
HOCl	6	O	3	2	V-shape	Polar

For number of valence electrons, it is the number of electrons present in outermost shell.

VSEPR electron groups on central atom is the number of electron pairs around the central atom.

Number of bonding groups means that how many electrons are making bonds.

Molecular geometry tells about the shape of the molecule.
