Question

Write the number of covalent bonds in the molecule of Butane, ${\mathrm{C}}_4{\mathrm{H}}_{10}$.

Answer 1

Butane:

• Butane is an alkane, having chemical formula ${\mathrm{C}}_4{\mathrm{H}}_{10}$ is a hydrocarbon that consists of $4$ carbon atoms and $10$ hydrogen atoms.
• Its structure is shown below.

• From the structure, it is clear that there are $3\mathrm{C}-\mathrm{C}$ covalent bonds.
• Also, there are $10\mathrm{C}-\mathrm{H}$covalent bonds.
• Total covalent bonds in ${\mathrm{C}}_4{\mathrm{H}}_{10}=13$

Hence, the number of covalent bonds in the molecule of Butane, ${\mathrm{C}}_4{\mathrm{H}}_{10}$ is $\mathbf{13}$.
