`C_(6)H_(5)-CH=CHCHO overset((X))rarr C_(6)H_(5)CH=CH_(2)OH` In the above sequence (X) can be:A. `N_(2)//Ni`B. `K_(2)Cr_(2)O_(7)//H^(+)`C. `NaBH_(4)`D. Both`(a)`and`(c )` |

Answer» Correct Answer - C `NaBH_(4)`and `LiAH_(4)`attack only carbony`1` group and reduce it into alcohol group. They do not attack on double bond. `underset("cinnamic aldehyde")(C_(6)H_(5)-CH=CHCHO) overset(NaBH_(4))rarr underset("cinnamic alcohol")(C_(6)H_(5)-CH=CH.CH_(2)OH)` Whereas `H_(2)//Ni` affects double bond and `K_(2)Cr_(2)O_(7)//H^(+)`carries oxidation. |
