Question

Match the isomers given in column I with their names given in column II and mark the appropriate choice.

Column I		Column II
A		i	2 - Bromo - 3 - methylbutane
B		ii	2 - Bromopentane
C		iii	1 - Bromo - 3 - methylbutane
D		iv	1 - Bromo - 2 -methylbutane

• A. $(A)\to (iii)$, $(B)\to (i)$, $(C)\to (iv)$, $(D)\to (ii)$
• B. $(A)\to (iv)$, $(B)\to (iii)$, $(C)\to (ii)$, $(D)\to (i)$
• C. $(A)\to (i)$, $(B)\to (ii)$, $(C)\to (iii)$, $(D)\to (iv)$
• D. $(A)\to (ii)$, $(B)\to (iii)$, $(C)\to (iv)$, $(D)\to (i)$

Answer 1

Answer: (D)

IUPAC system is one of the systematic methods of naming organic compounds.
The IUPAC name of option A is 2 - Bromopentane.
IUPAC name of the structure in option B is 1 - Bromo $-3-$ methylbutane.
IUPAC name of the structure in option $C$ is 1 - Bromo $-2-$ methylbutane.
IUPAC name of the structure in option D is 2 - Bromo $-3$ - methylbutane.
