Interpretation Introduction

To choose: The best Lewis structure for ${\mathrm{CH}}_{3}SOC{H}_3$ using the formal charge.

a) $H--\stackrel{H}{\stackrel{|}{\underset{H}{\underset{|}{C}}}}==\stackrel{\stackrel{••}{{}_{•}^{•}{O}_{•}^{•}}}{\stackrel{\parallel }{S}}--\underset{H}{\underset{|}{\stackrel{H}{\stackrel{|}{C}}}}--H$

b) $H--\stackrel{H}{\stackrel{|}{\underset{H}{\underset{|}{C}}}}==\stackrel{\stackrel{••}{{}_{•}^{•}O}}{\stackrel{\parallel }{\underset{••}{S}}}--\underset{H}{\underset{|}{\stackrel{H}{\stackrel{|}{C}}}}--H$

c) $H--\stackrel{H}{\stackrel{|}{\underset{H}{\underset{|}{C}}}}--\stackrel{\stackrel{••}{{}_{•}^{•}{O}_{•}^{•}}}{\stackrel{|}{\underset{••}{S}}}--\underset{H}{\underset{|}{\stackrel{H}{\stackrel{|}{C}}}}--H$

d) $H--\stackrel{H}{\stackrel{|}{\underset{H}{\underset{|}{C}}}}==\stackrel{\stackrel{••}{{}_{•}^{•}{O}_{•}^{•}}}{\stackrel{|}{\underset{}{S}}}--\underset{H}{\underset{|}{\stackrel{H}{\stackrel{|}{C}}}}--H$
