We can use Lewis dot structures to determine bonding patterns in molecules. the 2 outer C atoms have a hybridization of "sp2", the H atoms have a hybridization of "s", and the 2 C atoms in between have "sp" Chemistry. So, try to add more than one bond to decide whether central atom can achieve an octet or not! Hybridization stands for mixing atomic orbitals into new hybrid orbitals. The central atom is S. Determine the hybridization at each of the 2 labeled carbons. And each of these four molecules are so broadly we can say, if you have, they've surrounded by four electrons. Hence the shape is tetrahedral.AsF5:The central atoms (As) has five bond pairs and no lon∈ pair. The hybridization of the S atom is sp hybridized.
