The number of sigma bonds in ethane formed by the overlap of \[s{{p}^{3}}\] and s orbitals is

A)  5                                            

B)  6

C)  7                                            

D)  4

Correct Answer: B

Solution :

                 Structure of \[{{C}_{2}}{{H}_{6}}\]is : The C-atoms in ethane are \[s{{p}^{3}}\]hybridized so, the sigma bond between C?C atoms is \[s{{p}^{3}}-s{{p}^{3}}\]sigma bond and the bond formed  between C and H are \[s{{p}^{3}}-s\]sigma bond Hence, there are \[6\,s{{p}^{3}}-s\]sigma bonds in ethane.
