As indicated by the prefix "tetra" in the compound name, each molecule of carbon tetrafluoride contains 4 fluorine atoms.4
Two lone pair on the central selenium and three lone pairs on each chlorine. So total of eight lone pairs.
The answer is 2 since the Oxygen is double bonded with a carbon O=C
The factors affecting the shape of the molecules are the bonded e and the lone pairs of electrons
Noe, Hydrogen sulfide has two non-bonded pairs of electrons.
Lone-pair electrons, Bonded pairs of electrons
There are exactly three electron pairs attached to the Boron atom, each one of them bonded to a chlorine atom as well.
1molecule of C2H6 contains 2 carbon atoms

A common misconception is that it's an element. However, it is a compound. It contains to bonded Cl atoms. H, O, F, Br, I, and N also behave like this. You will never find them in their pure form as single atoms, they will always come in covalently bonded pairs.
There are three lone pairs present in chlorine atom
bonded
Non bonded pairs have a higher force of repulsion than bonded pairs, as the bonded pairs also feel the pull of another positive nucleus. The shape of a molecule is distorted. 2 example - NH3 (one lone pair) & H2O (2 lone pairs). NH3 is trigonal pyramidal while H2O is bent.
It has 3 bonded pairs with no lone pairs. These bonded pairs repel evenly between each electron pair. So it is a trigonal planar shape.
H|H-C-C-H_ _ O ::|HThe hydrogen are all single bonded. Oxygen is double-bonded to carbon with two sets of lone pair electrons.
sp3d hybridization for 5 electron pairs (2 lone pairs and 3 bonded pairs).
