Answer:
single covalent bond
Explanation:
There are 2 broadly types of chemical bonds present:
<u>1. Covalent bond:</u> This bond is present when there is sharing of electrons between two elements.
<u>2. Ionic bond:</u> This type of bond is formed when there is a complete transfer of electrons from one element to another element. In this bonding one element is always a metal and another is a non-metal.
We are given that a carbon atom is forming two bonds with hydrogen and rest two with carbon atoms. Carbon and hydrogen both are non-metals and hence, the bonds between them will be <u>purely covalent in nature.</u>
Also, the valency of the carbon atom is 4. Thus, in the given case, the carbon atom is bonded to 2 hydrogen atoms and 2 carbon atoms. <u>Thus, they all must be single bond.</u>
Thus, there exist <u>single covalent bond</u> between the two carbon atoms.
