Question

Explain the following terms with example.

1. Alkane
2. Covalent bond

Answer 1

1. Alkanes are the simplest family of hydrocarbons.
   It consists of single-bonded carbon and hydrogen atoms.
   The general formula for alkanes is $C_n{H}_{2n+2}$. Methane, ethane, and propane are examples of alkane.
2. A covalent bond is a chemical bond that involves the sharing of electron pairs between the atoms.
   These electron pairs are the stable balance of attractive and repulsive forces between the atoms.
   Example- In water $H_{2}O$,the covalent bond is formed by sharing electrons between hydrogen and oxygen atoms.
