In the following skew conformation of ethane, \(H'-C-C-H"\) dihedral angle is......\(^o\)

- A \(58\)
- B \(120\)
- C \(149\)
- D \(151\)
Answer & Solution
Correct Answer
(C) \(149\)
Step-by-step Solution
Detailed explanation
Dihedral angle is then angle between bond pairs present on adjacent atoms. \(H'-C-C-H''\) Hence angle between \(H' - C - C - H"\) is \(({120^o} + {29^o}) = {149^o}\)
