A chemical graph is a mathematical representation of a chemical compound
in which atoms and bonds are represented by nodes and lines
respectively. Chemists have developed a number of useful tools from
graph theory, such as topological index (TI) is structural descriptor or
connectivity index used to express molecular size, branching, heat of
formation, boiling points, strain energy, toughness and acyclicity. The
Topological index is beneficial to establish an association between
arrangement and chemical properties of chemical compounds without
performing any testing. It is characterized into various categories like
degree, distance, spectrum and eccentricity based. This paper consists
of computation of multiplicative degree based topological indices namely
multiplicative Zagreb indices, multiplicative atom bond connectivity
index and generalized multiplicative geometric arithmetic index for
SiC_3-I[j, k] and SiC_3-II[j, k].
