QUESTION: 1

In the reaction, 

the product C is

(JEE Main 2014)

Solution:

The complete serise of reaction can be respresented as 

QUESTION: 2

A compound with molecular mass 180 is acylated with CH3COCI to get a compound with molecular mass 390. The number of amino groups present per molecule of the former Compound is

Solution:


Since, each—COCH3 group displace one H-atom in the reaction of one mole of  with one  —NH2 group the molecilar mass increase with 42 unit. Since, the mass increase by (390 - 180) = 210, hence the number of —NH2 group is  

QUESTION: 3

An organic compound A upon reacting with NH3 gives B. On heating, B gives C. C in the presence of KOH reacts with Br2 to give CH3CH2NH2. A is

(JEE Main 2013)

Solution:


QUESTION: 4

The strongest acid amongst the following compounds is

(AIEEE 2011)
Solution:

- I effect exerting (electron withdrawing) groups increase the acidic strength of an acid by withdrawing electron density towards itself, they weakning O-H bond and thus, the release of H+ ion by an acid becomes easier.
Whereas + I effect excerting (e- releasing) groups decreases the acide strength by donating electron density to O-atom.
Further, - I effect decreases with distance. Thus, the acidic strength of the given acids would be :


Hence,  is most acidic and strongth acid than other given compunds.

QUESTION: 5

Sodium ethoxide has reacted with ethanoyl chloride. The compound that is produced in the a bove reaction is

(AIEEE 2011)
Solution:



This is by SN reaction. Cl- is a better leaving group than C2H5O- and then ethyl ethanoate is formed.

QUESTION: 6

A liquid was mixed with ethanol and a drop of concentrated H2SO4 was added. A compound with a fruity smell was formed. The liquid was

(AIEEE 2009)
Solution:


Fruity smell is the characteristic property of ester, thus the above reaction leads to the formation of ester.

This reaction is called esterification.

QUESTION: 7

The general formula CnH2nO2 could be for open Chain

(AIEEE 2003)
Solution:

CnH2nO2 is general form ula for open chain carboxylic acids and esters.

QUESTION: 8

When is reduced with LiAIH4, the compound obtained will be

(AIEEE 2003)
Solution:

LiAIH4 reduces —COOH to —CH2OH without affecting bond.

QUESTION: 9

Ethyl isocyanide on hydrolysis in acidic medium generates

(AIEEE 2003)
Solution:

QUESTION: 10

End product of the following reaction is

(AIEEE 2002)
Solution:
