Answer 1

Answer #1

Resonance structure is shown by ' $\leftrightarrow$ '
HBr ( 1 mole ) , Peroxides
No rotation ( The molecule can be divided in to two similar halves. So the optical activity due to first Chiral center is cancelled by the second Chiral center )
CH₃C $\equiv$ CCH₂CH₃ ( 2-Pentene )
Second one is more stable alkene ( Highly substituted alkene is more stable .
