In the following skew conformation of ethane, H’–C–C–H" dihedral angle is:
(The Newman projection shows a 29$^\circ$ offset from eclipsed)
(1) 58$^\circ$
(2) 149$^\circ$
(3) 151$^\circ$
(4) 120$^\circ$
Show Answer
Answer: (2)
Solution
Angle between H’ and H" = 120$^\circ$ + 29$^\circ$ = 149$^\circ$.
