Question

1. Ethane, with the molecular formula C2H6 has: (a) 6 covalent bonds (b) 8 covalent bonds (c) 7 covalent bonds (d) 9 covalent bonds​

Answer 1

$\huge{ \underline {\sf {\green{a}{ \pink{n} {\red{ s}{\blue{w} {\purple{e}{{r}}}}}}}}}$

(b) 8 covalent bonds.

Ex.

From the above structure, we can see that the Ethane molecule has 6 C-H covalent bonds and one C-C covalent bond. Therefore, on adding the covalent bonds of C-C and C-H covalent bonds, we can say that the Ethane molecule has 7 covalent bonds. Hence the correct answer is (B) 7 covalent bonds.
