II and III

Text Solution

Verified by Experts

The correct Answer is:
C

II. `(CH_(3))_(2)underset(OH)underset(|)C-CH_(2)-CHO underset("Elcb")overset(Delta)to underset(("saytzeff elimination"))((CH_(3))_(2)C=CH-CHO)`
III. `(CH_(3))_(2)CHCH_(2)-underset(F)underset(|)CH-CH_(3)underset(Delta)overset(CH_(3)O^(-)Na^(+))to underset(("Hoffmann elimination"))((CH_(3))_(2)CHCH_(2)-CH=CH_(2))`
IV. `(CH_(3))_(2)CH-underset(Br)underset(|)CH-CH_(3)overset((CH_(3))_(3)CO^(-)K^(+))to underset(("Hoffmann elimination"))((CH_(3))_(2)CH-CH=CH_(2))`
