Part C: CS\u2082<\/strong><\/h3>\n\n\n\n
    \n
  • Lewis Structure of CS\u2082<\/strong>: Carbon is the central atom bonded to two sulfur atoms. Each C=S bond is a double bond<\/strong>.<\/li>\n\n\n\n
  • There are no lone pairs<\/strong> on the central carbon atom.<\/li>\n\n\n\n
  • Each double bond counts as one electron group<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    Part D: CH\u2084<\/strong><\/h3>\n\n\n\n
      \n
    • Lewis Structure of CH\u2084<\/strong>: Carbon is the central atom bonded to four hydrogen atoms via single bonds<\/strong>.<\/li>\n\n\n\n
    • There are no lone pairs<\/strong> on the central carbon atom.<\/li>\n\n\n\n
