Question

Match the following names of reagents given in Column II to bring about the conversions given in Column I and choose the correct option from the codes given below.

Column I(Conversion)		Column II(Reagents)
A	Hexan-1-ol to hexanal	1	$C_5{H}_5\stackrel{+}{N}HCr{O}_{3}C{l}^{-}(PCC)$
B	Cyclohexanol to cyclohexanone	2	$Cr{O}_3$ in the presence of acetic anhydride
C	$p$-fluorotoluene to $p$-fluorobenzaldehyde	3	$K_{2}C{r}_2{O}_7$ in acidic medium

• A. A - (1) , B -(2) , C -(3)
• B. A - (2) , B -(3) , C -(1)
• C. A - (1) , B -(3) , C -(2)
• D. A - (2) , B -(1) , C -(1)

Answer 1

Answer: (C)

$A\to 1,B\to 3,C\to 2$
Hexan-1-ol $\stackrel{\text{ PCC }}{\to }$ Hexanal
Cyclohexanol $\underset{Cr{O}_3}{\overset{K_{2}C{r}_2{O}_7\text{ (acidic) }}{\to }}$ Cyclohexanone
$p$-fluorotoluene $\underset{(C{H}_{3}COO{)}_{2}O}{\overset{Cr{O}_3}{\to }}p$-fluorobenzaldehyde
