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	$C _{5} H _{5} \overset{+}{N}HCrO _{3} Cl ^{-}( PCC )$
B	Cyclohexanol to cyclohexanone	2	$CrO _{3}$ in the presence of acetic anhydride
C	$p$-fluorotoluene to $p$-fluorobenzaldehyde	3	$K _{2} Cr _{2} O _{7}$ 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)

$A \rightarrow 1, B \rightarrow 3, C \rightarrow 2$
Hexan-1-ol $\xrightarrow{\text { PCC }}$ Hexanal
Cyclohexanol $\xrightarrow[CrO_3]{ K _{2} Cr _{2} O _{7} \text { (acidic) }}$ Cyclohexanone
$p$-fluorotoluene $\xrightarrow[(CH_3COO)_2O]{ CrO _{3}} p$-fluorobenzaldehyde
