1.	The `IUPAC` name of `CH_(2) = CHCH(CH_(2)CH_(3))underset(Br)underset(\|)(C)=CH_(2)` isA. (1) `4`-bromo-`3`-ethylpenta-`1,4`-dieneB. (2) `2`-bromo-`3`-ethylpanta-`1,4`-dieneC. (3) `2`-bromo-`3`-ethylpenta-`1,5`-dieneD. (4) non of these
Answer» Correct Answer - B The compound contains two `C=C` bonds, i.e., it is an alkadiene. The numbering starts from the end nearer to the double bond. `overset(5)(CH_(2))=overset(4)(CH)-underset("2-Bromo-3-ethylpenta-1,5-diene")(underset(CH_(2)CH_(3))underset(\|)overset(3)(CH)-underset(Br)underset(\|)overset(2)(C)=overset(1)(CH_(2)))` The names of substituents should be listed alphabetically.
