Question

The reagent required to convert 2-Chloro-2-methylbutane into 2-Methylbut -2-ene is

• A. Alcoholic $NaOH$
• B. Aqueous $NaOH$
• C. Tert-butoxide/tert-butyl alcohol
• D. Methanol

Answer 1

The correct option is A Alcoholic $NaOH$

The alkene required is saytzeff product. So,it requires a strong base which is alcoholic $NaOH$ not $aq.NaOH$.
Tert-butoxide being a bulky basen gives Hofmann's product, 2-Methylbut -1-ene. Methanol is not a strong base that may undergo substitution. The correct reagent to get the required product is alcoholic $NaOH$.
