Which of the following is/are CORRECT for the two molecules shown?
Show Hint
Stereoisomers have the same connectivity of atoms but differ in spatial arrangement. Diastereoisomers are stereoisomers that are not mirror images of each other.
Updated On: Sep 8, 2025
- They are stereoisomers
- Each of them has two stereogenic centers
- They are mirror images of each other
- They are diastereoisomers
Hide Solution
Verified By Collegedunia
The Correct Option is A, D
Solution and Explanation
Step 1: Analyzing the structures.
The two molecules shown in the image are organic compounds that differ in their spatial arrangement around the stereocenters. Let's examine their relationship based on stereochemistry.
Step 2: Understanding the options.
- (A) Correct: These molecules are stereoisomers because they have the same molecular formula and connectivity of atoms but differ in their spatial arrangement of atoms, which makes them stereoisomers.
- (B) Incorrect: The two molecules shown each have only one stereocenter, not two. A stereogenic center is a carbon atom bonded to four different substituents.
- (C) Incorrect: The molecules are not mirror images of each other. Mirror images are enantiomers, but these molecules are not enantiomers because they are not related by reflection in a mirror.
- (D) Correct: These molecules are diastereoisomers. Diastereoisomers are stereoisomers that are not mirror images of each other. Since the two molecules are not mirror images but differ in their spatial arrangement, they are diastereoisomers.
Final Answer: \[ \boxed{\text{(A) and (D) are correct.}} \]

The vector, shown in the figure, has promoter and RBS sequences in the 300 bp region between the restriction sites for enzymes X and Y. There are no other sites for X and Y in the vector. The promoter is directed towards the Y site. The insert containing only an ORF provides 3 fragments after digestion with both enzymes X and Y. The ORF is cloned in the correct orientation in the vector using the single restriction enzyme Y. The size of the largest fragment of the recombinant plasmid expressing the ORF upon digestion with enzyme X is ........... bp. (answer in integer)
