Question

An organic compound (X) after hydrogenation gives 2-Methylbutane. Reaction of 1 mole of 'X' with Na metal
gives
1
2
mol of Hą gas. 'X' also gives positive test with Br, water. Identify the structure of 'X'.​

Answer 1

Answer:

CH2=C∣−CH3CH2−CH3            2-Methylbut-1-ene

CH3−C∣=CH3CH−CH3              2-Methylbut-2-ene

CH5−C∣HCH3−CH=CH2         3-Methylbut-1-ene

The structures of all the alkenes which on hydrogenation give 2 - methylbutane are as shown.
