Question

state whether the following statement are true or false:
⭕ there are 7 covalent bond in the structure of ethane molecules.​

Answer 1

Answer:

TRUE

Explanation:

WE CAN FIND THE NUMBER OF COVALENT BONDS IN ALKANES BY ONE MORE THAN SUM OF NUMBER OF HYDROGENS AND CARBONS

$c_{2} h_{4} = 2 + 4 + 1 \\ \: \: \: \: \: \: \: \: \: \: = 7$

Answer 2

It is true that there are 7 covalent bonds in the structure of ethane molecules.

• The covalent bonds can be formed by the carbon atoms because it's valency is 4.

• So, a carbon can form 4 individual covalent bonds.

• Now,there are two carbon atoms present in an ethane molecules.

• The two carbons form a covalent bond between them and 6 covalent bonds with the hydrogen atoms.

• So,the total number of covalent bonds are :

= 1 C-C bond + 6 C-H bonds

= 7 covalent bonds.
