An organic compound (A) (molecular formula (C₈H₁₆O₂) gives a carboxylic acid (B) upon hydrolysis by dilute sulphuric acid and an alcohol (C). Oxidation of(C) with chromic acid produces(B). (C) on dehydration gives but-1-ene. Compound B is:

1.	Butanoic acid	2.	Propanoic acid
3.	Butanol	4.	Propanoic acid

Arrange them in increasing order according to their reactivity towards HCN: 

Acetaldehyde, Acetone, Di-tert-butyl ketone and Methyl tert-butyl ketone;

1. Di-tert-butyl ketone > Methyl tert-butyl ketone > Acetone > Acetaldehyde

2. Di-tert-butyl ketone < Methyl tert-butyl ketone < Acetone < Acetaldehyde

3. Di-tert-butyl ketone < Acetone < Methyl tert-butyl ketone < Acetaldehyde

4. Methyl tert-butyl ketone < Di-tert-butyl ketone < Acetone < Acetaldehyde

Phthalic acid on heating with SOCl₂  gives:

An organic compound (A) contains 69.77% carbon, 11.63% hydrogen, and rest oxygen. The molecular mass of the compound is 86. It does not reduce Tollens’ reagent but forms an addition compound with sodium hydrogen sulphite and gives a positive iodoform test. On vigorous oxidation, it gives ethanoic and propanoic acid. Compound A would be:

1. Pentan-2-one

2. Butanone

3. 3-Methylbutanone

4. Propan-2-ol

Arrange the following compounds in increasing order of their boiling points:

CH₃CHO, CH₃CH₂OH, CH₃OCH₃, CH₃CH₂CH₃

$1. {\mathrm{CH}}_3\mathrm{CHO}< {\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH} <{\mathrm{CH}}_3{\mathrm{OCH}}_3< {\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_3$
$2. {\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_3<{\mathrm{CH}}_3{\mathrm{OCH}}_3< {\mathrm{CH}}_3\mathrm{CHO}<{\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH}$
$3. {\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_3>{\mathrm{CH}}_3{\mathrm{OCH}}_3 >{\mathrm{CH}}_3\mathrm{CHO}>{\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH}$
$4. {\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_3< {\mathrm{CH}}_3\mathrm{CHO}<{\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH} <{\mathrm{CH}}_3{\mathrm{OCH}}_3$

The correct sequence of increasing orders of reactivity in nucleophilic addition reaction is:

1. Butanone < Propanone < Propanal < Ethanal

2. Butanone > Propanone > Propanal > Ethanal

3. Butanone < Propanal < Propanone < Ethanal

4.  Propanal < Propanone < Ethanal < Butanone 

Arrange the following compounds in increasing order of their reactivity in nucleophilic addition reactions :Benzaldehyde, p-Tolualdehyde, p-Nitrobenzaldehyde, Acetophenone.

1. Acetophenone < Benzaldehyde <  p-tolualdehyde < p-Nitrobenzaldehyde

2. Acetophenone < p-tolualdehyde < Benzaldehyde < p-Nitrobenzaldehyde

3. Acetophenone > p-tolualdehyde > Benzaldehyde < p-Nitrobenzaldehyde

4. Acetophenone < p-tolualdehyde <  p-Nitrobenzaldehyde < Benzaldehyde 

What will be the IUPAC names of the following compound ?
