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.
