The cumulated alkadiene is
C.
(i) The alkadienes in which two double bonds are on adjacent carbon atoms are known as cumulated alkadienes.
(ii) The alkadienes, having alternate single and double bonds are known as conjugated dienes.
(iii) The alkadienes having two double bonds seperated by more than one single bond are known as isolated dienes.
The IUPAC name of
is
4-bromo-2-chloro-5-iodo-1-fluorobenzene
2-carbamoylhex-3-enal
1-bromo-2-chloro-3-fluoro-6-iodobenzene
2-bromo-1-chloro-5-fluoro-3-iodobenzene
Assertion (A): Reaction of 1-butene with HBr gives 1-bromobutane as major product.
Reason (R): Addition of hydrogen halides to alkenes proceeds according to Markownikoffs rule.
The correct answer is
A and R are correct and R is the correct explanation of A
A and R are correct but R is not the correct explanation of A.
A is correct but R is not correct
A is not correct but R is correct
