Question

Identify $\left(X\right),\left(Y\right)$ and $\left(Z\right)$ in the given reaction. $X+Y\stackrel{Z}{\to }\underset{3-Hydroxybutanal}{C{H}_3-\stackrel{OH}{\stackrel{|}{C}}H-C{H}_2}-CHO$

• A. $X=HCHOY=C{H}_{3}CHOZ=KOH$
• B. $X=C{H}_{3}CHOY=C{H}_{3}CHOZ=NaOH$
• C. $X=C{H}_{3}C{H}_{2}OHY=HCHOZ=H_{2}S{O}_4$
• D. $X=C{H}_{3}C{H}_{2}CHOY=HCHOZ=Dryether$

Answer 1

The correct option is B $X=C{H}_{3}CHOY=C{H}_{3}CHOZ=NaOH$

$\underset{\left(X\right)}{C{H}_3}CHO+\underset{\left(Y\right)}{C{H}_3}CHO\underset{\left(Z\right)}{\overset{NaOH}{\to }}\underset{\left(Aldolcondensation\right)}{C{H}_3-\stackrel{OH}{\stackrel{|}{C}}H-C{H}_2-CHO}$

Option B is correct.
