Question

draw electron dot structure of H2S and CO2
propanol

Answer 1

valence no of electron of S =6
valence no of electron of H =1
H2S=. H. H.
S......

Answer 2

Electron dot structure denotes the presence of valence electrons on molecules.

• The electron dot structure gives an idea of the presence of valence electrons and the structure of the molecule.

• The first molecule which is hydrogen sulfide contains two molecules of hydrogen and one molecule of sulfur.

• The sulfur molecule contains two lone pairs of electrons and therefore, the structure appears to be bent in shape.

• In the case of carbon dioxide, there are two molecules of oxygen and one molecule of carbon.

• Each oxygen contains two lone pairs of electrons and is attached to a carbon atom via a double bond. Therefore, carbon dioxide forms a linear structure.
