Homework Answers
The Lewis structure of SiS2 is given by
a. Out of eight electron pairs, four are engaged in bonding.and hence total four lone pairs are present in the molecule.
b. Two electron domains present, due to two double bonds.
c. As the Si atom is SP hybridised, electronic shape is linear.
d. Molecular shape includes all three atoms. As a whole, molecular shape is linear.
e. No resonance is observed.
f. Si is has a lower electronegativity value compared to S. This means the molecule has polar bonds, however, since the polar bonds are equal and opposite to each other (both point away from the Si molecule in opposite directions) they “cancel out”.Hence as a whole, the molecule is non-polar.
g. Hybridization is SP.
