Question

find Å and B in Following reashions H₂ C - CH A alekoh Poroxide B HI Br CH2​

Answer 1

propeneCH3−CH=CH2HBr1−propyl bromideCH3−CH2−CH2−Bralc.KOHpropeneCH3−CH=CH2+KBr+H2O

When propene reacts with HBr it undergoes hydrohalogenation reaction to form 1−bromo propane (A) as a product.

When compound (A) reacts with alc.KOH, it undergoes β-elimination reaction to form propene (B) as a product
