Vedclass · Answer

(B) The reaction of $1-bromo-1,2-diphenylpropane$ with $alc.KOH$ is a dehydrohalogenation reaction ($E2$ mechanism).This reaction leads to the formation of an alkene by removing $H$ and $Br$ from adjacent carbons.The major product is the more stable alkene,which is the trans-isomer of $1,2-diphenylprop-1-ene$.In the trans-isomer,the bulky phenyl groups are on opposite sides of the double bond,minimizing steric hindrance.Thus,the product $A$ is $1,2-diphenylprop-1-ene$ (trans-isomer).

The reaction $CH_3-CH(C_6H_5)-CH(Br)-C_6H_5 \xrightarrow{alc.KOH} A$. Identify the product $A$.
