Structural formula of propane (C3H8; primary carbons are highlighted red)

In

carbon chain. In case of an alkane, three hydrogen atoms are bound to a primary carbon (see propane in the figure on the right). A hydrogen atom could also be replaced by a hydroxy group (−OH), which would make the molecule a primary alcohol.[2]
