Web12 Jul 2024 · We introduced the three simplest alkanes—methane (ch4), ethane (c2h6), and propane (c3h8)—in chapter 4 covalent bonding and simple molecular compounds, section 4.6 introduction to organic chemistry. Chain alkanes, cycloalkanes, and branched alkanes. Collectively, they are called unsaturated hydrocarbons. WebKey points. An acid and alkali will neutralise each other and produce a salt and water. This is called a neutralisation reaction. The name of the salt produced can be worked out from the names of ...
