Question

Match List - I with List - II: 

Choose the correct answer from the options given below:
 

• A. \( {(A)-(I)}, {(B)-(II)}, {(C)-(IV)}, {(D)-(III)} \)
• B. \( {(A)-(II)}, {(B)-(I)}, {(C)-(III)}, {(D)-(IV)} \)
• C. \( {(A)-(I)}, {(B)-(III)}, {(C)-(II)}, {(D)-(IV)} \)
• D. \( {(A)-(III)}, {(B)-(I)}, {(C)-(IV)}, {(D)-(II)} \)

Hint:

When naming organic compounds, look for the longest chain and the position of substituents such as methyl or ethyl groups, along with the positions of double bonds.

Answer 1

The Correct Option is C

We will match the structure in List I with its corresponding IUPAC name in List II. 
- (A) The structure corresponds to 4-Methylpent-1-ene. This is because the longest chain is 5 carbons, with a methyl group at position 4 and a double bond at position 1. 
- (B) The structure corresponds to 4,4-Dimethylheptane. The central carbon is attached to two methyl groups, and the longest chain has 7 carbon atoms. 
- (C) The structure corresponds to 3-Ethyl-5-methylheptane. It is a heptane chain with an ethyl group at position 3 and a methyl group at position 5. 
- (D) The structure corresponds to 2-Methyl-1,3-pentadiene. It is a pentadiene chain with a methyl group at position 2 and double bonds at positions 1 and 3. Thus, the correct matching is (A)-(I)}, (B)-(III), (C)-(II), (D)-(IV).
