The correct answer is:<\/p>\n\n\n\n

Tetrahedral, trigonal pyramidal<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

The molecule CH\u2083NH\u2082, methylamine, consists of two central atoms: carbon (C)<\/strong> and nitrogen (N)<\/strong>. Each of these atoms has its own molecular geometry based on the number of bonded atoms and lone pairs of electrons around them.<\/p>\n\n\n\n

1. Geometry Around Carbon (C): Tetrahedral<\/strong><\/h4>\n\n\n\n
    \n
  • The carbon atom in CH\u2083NH\u2082 is bonded to three hydrogen atoms<\/strong> and one nitrogen atom<\/strong>. So, it has four groups<\/strong> attached to it.<\/li>\n\n\n\n
  • According to the Valence Shell Electron Pair Repulsion (VSEPR) theory<\/strong>, when an atom has four bonded atoms (or electron groups) and no lone pairs<\/strong>, the ideal molecular geometry is tetrahedral<\/strong>.<\/li>\n\n\n\n
  • In a tetrahedral shape, the four groups are arranged around the carbon atom at approximately 109.5\u00b0 angles to minimize repulsion.<\/li>\n\n\n\n
  • Thus, the molecular geometry around the carbon atom in CH\u2083NH\u2082 is tetrahedral<\/strong>.<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    2. Geometry Around Nitrogen (N): Trigonal Pyramidal<\/strong><\/h4>\n\n\n\n
    \n\n\n\n

    Summary:<\/h3>\n\n\n\n
      \n
    • Carbon in CH\u2083NH\u2082: Four single bonds, no lone pairs \u2192 Tetrahedral<\/strong><\/li>\n\n\n\n
    • Nitrogen in CH\u2083NH\u2082: Three bonds + one lone pair \u2192 Trigonal pyramidal<\/strong><\/li>\n<\/ul>\n\n\n\n

      This distinction is important because the molecular shape affects physical properties like polarity and chemical reactivity. The tetrahedral shape around carbon is common in many organic compounds with single bonds, while trigonal pyramidal geometry around nitrogen is typical for amines like CH\u2083NH\u2082.<\/p>\n\n\n\n
