Enter the molecular formula for butane, C4H10 Express your answer as a chemical formula.<\/p>\n\n\n\n

The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The molecular formula for butane<\/strong> is C\u2084H\u2081\u2080<\/strong>.<\/p>\n\n\n\n

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

Butane is an organic compound and is part of the alkane<\/strong> family, which are hydrocarbons consisting only of carbon (C) and hydrogen (H) atoms, with single bonds between carbon atoms. The formula C\u2084H\u2081\u2080<\/strong> indicates that butane has four carbon (C) atoms and ten hydrogen (H) atoms.<\/p>\n\n\n\n

Alkanes follow the general molecular formula C\u2099H\u2082\u2099\u208a\u2082<\/strong>, where “n” is the number of carbon atoms. For butane, “n” equals 4, which satisfies the formula C\u2084H\u2081\u2080<\/strong>.<\/p>\n\n\n\n

Butane exists in two structural forms:<\/p>\n\n\n\n

    \n
  1. n-butane<\/strong> (normal butane) \u2013 This is a straight-chain alkane where the carbon atoms are connected in a continuous chain.<\/li>\n\n\n\n
  2. iso-butane<\/strong> (isobutane) \u2013 This is a branched-chain alkane where the carbon chain branches out at one point, forming a more compact structure.<\/li>\n<\/ol>\n\n\n\n

    Despite their structural differences, both forms of butane share the same molecular formula C\u2084H\u2081\u2080<\/strong>. The difference between the two isomers lies in the arrangement of the atoms, which affects their physical and chemical properties. Butane is commonly used as a fuel, in lighters, and in propane-butane gas mixtures for heating and cooking.<\/p>\n\n\n\n

    Structure:<\/h3>\n\n\n\n
      \n
    • In n-butane<\/strong>, the carbon atoms are linked in a continuous chain.<\/li>\n\n\n\n
    • In iso-butane<\/strong>, the structure is branched, with three carbon atoms forming a chain and the fourth carbon atom branching off.<\/li>\n<\/ul>\n\n\n\n

      Butane is a colorless, odorless gas at room temperature and pressure and is highly flammable.<\/p>\n\n\n\n

      Here is the image illustrating the molecular structures of n-butane<\/strong> and iso-butane<\/strong>, both having the molecular formula C\u2084H\u2081\u2080<\/strong>. The image shows the difference in their structure: n-butane is a straight-chain alkane, while iso-butane is branched.
