Question 6.CC.5: Draw the Lewis structures for CS2....
Draw the Lewis structures for CS_2.
Step-by-Step
The central atom is C.
S C S
Determine the total number of valence electrons.
\begin{aligned} 1\ C \times 4\ e^{-} & =4\ e^{-} \\ 2\ S \times 6\ e^{-} & =12\ e^{-} \\ \text {Total } & =\overline{16\ e^{-}} \end{aligned}
Attach each bonded atom to the central atom using a pair of electrons. Two bonding pairs use four electrons.
S:C:S
Place the 12 remaining electrons as lone pairs around the S atoms.
\underset{\cdot\cdot}{\overset{\cdot\cdot}{:\text{S}:}}C\underset{\cdot\cdot}{\overset{\cdot\cdot}{:\text{S}:}}To complete the octet for C, a lone pair of electrons from each of the S atoms is shared with C, which forms two double bonds.
{\overset{\cdot\cdot}{:\text{S}::}}C{\overset{\cdot\cdot}{::\text{S}:}}\quad\text{or}\quad\overset{\cdot\cdot}{\text{:S}}=C=\overset{\cdot\cdot}{\text{S:}}Related Answered Questions
