Question

The number of structural and configurational isomers of a brorno compound, C5 H9 Br, formed by the addition of HBr to 2-pentyne respectively, are (A) 1 and 2 (B) 2 and 4 (C) 4 and 2 (D) 2 and 1

Tardigrade Admin · Accepted Answer

CH3-C≡ C-CH2CH3 + HBr longrightarrow Therefore, two structural and four configurational isomers.

Q. The number of structural and configurational isomers of a brorno compound, $C_{5} H_{9} B r,$ formed by the addition of $H B r$ to $2$ -pentyne respectively, are

1 and 2

2 and 4

4 and 2

2 and 1

$C H_{3} - C \equiv C - C H_{2} C H_{3} + H B r ⟶$
Therefore, two structural and four configurational isomers.
