 (I)  (II)   (III)  (IV)  (V)  

Major Organic Chemistry - Question 4

Major product formed in the following reaction is:

Major Organic Chemistry - Question 5

The mechanism of the transformation involves:  

Major Organic Chemistry - Question 6

Major Organic Chemistry - Question 7

The major product of the following reaction is:

Major Organic Chemistry - Question 8

Consider the following:
   
Order of stretching frequency in IR-spectroscopy would be:           

Detailed Solution for Major Organic Chemistry - Question 8

Correct Answer :- a

Explanation : The stretching frequency increases with increase in the number of Pi bond which is present in the carbon bond. In case of triple bond there are two pi bond , in case of double bond there is only a single pi bond.

This is because with increase in the number of bond there is decrease in the atomic distance and hence there is more chance of stretching between the two atoms with respect to each other.

Major Organic Chemistry - Question 9

The major product formed in the following reaction is:

Major Organic Chemistry - Question 10

The major product formed in the reaction given below is:

Major Organic Chemistry - Question 11

Which is reducing sugar?

Detailed Solution for Major Organic Chemistry - Question 11

Ans: c

Explanation: A reducing sugar is any sugar that is capable of acting as a reducing agent because it has a free aldehyde group or a free ketone group. Ketoses must first tautomerize to aldoses before they can act as reducing sugars. The common dietary monosaccharides galactose, glucose and fructose are all reducing sugars.
