Question

Write the number of $\mathrm{C}$ and $\mathrm{H}$ atoms in a molecule of Decane.

Answer 1

Step 1: Introduction

Alkane is a saturated hydrocarbon that has Carbon-Carbon and Carbon-Hydrogen atoms that are only connected through single bonds.

The general formula of an alkane is ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2}$.

Where, $\mathrm{n}$ is the number of Carbon $\left(\mathrm{C}\right)$ atoms in alkane compound and,

$2\mathrm{n}+2$ tells about the number of Hydrogen $\left(\mathrm{H}\right)$ atoms in an alkane compound.

Step 2: Determination of number of Carbon atoms:

Dec represents ten-Carbon atom in a compound.

Step 3: Substituting the value of n = 10 in general formula:

The general formula is ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2}$

${\mathrm{C}}_{10}{\mathrm{H}}_{2\mathrm{x}10+2}={\mathrm{C}}_{10}{\mathrm{H}}_{22}$

The molecular formula of the Decane is ${\mathrm{C}}_{10}{\mathrm{H}}_{22}$.

Hence, the count of Carbon atom is ten and Hydrogen is twenty two.
