(CH_3)_(2)CHCH_(2)-underset(F)underset(|)(CH)-CH_(3)overset(CH_(3)O^(-)Na^(+))underset(Delta)rarr IV. (CH_3)_(2)CH-underset(Br)underset(|)CH-CH_(3)overset((CH_3)_(3)CO^(-)K^(+))rarr Which of these reaction(s) will not produce Hoffmann product ? |

Answer» I and II  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))` |
