Q. What is the product of $1, 4$ -addition in the reaction shown below?
$P h - C H = C H - C H = C H - P h H B r$

$P h - C H_{2} - C H = C H - B r ∣ C H - P h$

$P h - C H_{2} - B r ∣ C H - C H = C H - P h$

Correct answer is (a) $P h - C H_{2} - C H = C H - B r ∣ C H - P h$

Q. What is the product of 1,4 -addition in the reaction shown below? Ph−CH=CH−CH=CH−PhHBr​

Ph−CH2​−CH=CH−Br∣C​H−Ph

Ph−CH2​−Br∣C​H−CH=CH−Ph

Correct answer is (a) Ph−CH2​−CH=CH−Br∣C​H−Ph

Q. What is the product of $1, 4$ -addition in the reaction shown below?
$P h - C H = C H - C H = C H - P h H B r$

$P h - C H_{2} - C H = C H - B r ∣ C H - P h$

$P h - C H_{2} - B r ∣ C H - C H = C H - P h$

Correct answer is (a) $P h - C H_{2} - C H = C H - B r ∣ C H - P h$
