BaCO3 + H2SO4 --------> GAS(X)
CH2=CHBr + Mg/ether + X + WATER + LiAlH4 + HBr + ozonolysis --------------> P
TELL ALL POSSIBLE ANSWERS FOR P IN THE ABOVE PROCEDURE
(NOTE THE CARBON IN BARIUM CARBONATE IS SPECIFICALLY UNDERLINED TO DISTINGUISH IT FROM THE OTHER CARBON .DO THE SAME IN THE ANSWER ALSO)
X= CO2
CH2=CHBr+Mg/ETHER-->CH2=CHMgBr
CH2=CHMgBr+ CO2 +H20-->CH2=CH-COOH
CH2=CH-COOH + L.A.H-->CH2=CH-CH2-OH
CH2=CH-CH2-OH + H+-->CH2=CH-CH2+ (ALLYLIC CARBOCATION)
CH2=CH-CH2+ {R.S 1} <----> +CH2-CH=CH2 {R.S 2}....(RESONACE)
R.S 1 +Br- ----->PRODUCT1 ...DO ITS OZONOLYSIS( I HOPE U CAN DO IT)
R.S 2 + Br- ------->PRODUCT 2...DO ITS OZONOLYSIS
I HOPE NOW YOUR DOUBT IS REMOVED....BST OF LUCK FOR JEE
