Q. 15.0( 2 Votes )

Draw the electron dot diagram of chemical bonds in methane (CH4) and ethane (C2H6).

Answer :

Methane

The atomic number of carbon is 6. Its configuration is 2,4. Its outermost orbit contains 4 electrons. The atomic number of hydrogen is 1. Its configuration is 1. Its outermost orbit contains 1 electron. Carbon and hydrogen thus share these electrons, so that carbon acquires octet structure and hydrogen acquires duplet structure and become stable. This is a covalent compound.




Ethane


The atomic number of carbon is 6. Its configuration is 2,4. Its outermost orbit contains 4 electrons. The atomic number of hydrogen is 1. Its configuration is 1. Its outermost orbit contains 1 electron. In ethane, 2 Carbon and 6 hydrogens thus share these electrons, so that carbons acquire octet structure and hydrogens acquire duplet structure and become stable. This is a covalent compound.
