Question

ph-CH=CH-COOH + Br2
-A
the number of chiral carbons in 'A' are
(1) 1
(2) 2
(3) 3
(4) 4​

Answer 1

Correct answer is *3* . As usual, we count the no. of carbons in a particular reaction but if COOH is given then we have to count the *C* as carbon is also a part and share some proportion in the compound.

*All the best for your further exams!!!*

Answer 2

Answer:

Answer is 2.

Explanation:

for a carbon to be chiral it should be bonded to 4 different atoms. so here are only 2 chiral carbon atoms. Carbon of COOH is not counted because it has double bonded oxygen atom.
