Verified By Collegedunia
The Correct Option is D
Solution and Explanation
$CH_2 = CH_2 + HBr \longrightarrow \underset{X}{CH _{3}- CH _{2} Br}$
$\underset{X}{CH_3CH_2Br} { ->[{A KOH}][{-KBr}] \underset{ethyl\,alcohol \, Y}{CH_3CH_2OH}}$
$CH_3CH_2OH + NaCO_3 +I_2 { ->[{}][{(iodoform \,test)}] \underset{iodoform\,Z}{CHI3}} + HCOONa + NaI + CO_2 +H_2O$

- Ferrocene is:
An alkene X (\( C_4H_8 \)) on reaction with HBr gave Y (\( C_4H_9Br \)). Reaction of Y with benzene in the presence of anhydrous \( AlCl_3 \) gave Z which is resistant to oxidation with \( KMnO_4 + KOH \). What are X, Y, Z respectively?
- An alkene X (\( C_4H_8 \)) does not exhibit cis-trans isomerism. Reaction of X with \( Br_2 \) in the presence of UV light gave Y. What is Y?

Alkenes
In organic chemistry, an alkene is a hydrocarbon containing a carbon-carbon double bond.[1]
Alkene is often used as synonym of olefin, that is, any hydrocarbon containing one or more double bonds.

IUPAC Nomenclature of Alkenes
- An alkene or cycloalkene is indicated by the suffix (ending) ene.
- For the root name, the longest chain must include both carbon atoms of the double bond.
- The root chain must be numbered beginning at the end closest to a double bond carbon atom. If the double bond is in the chain's centre, the nearest substituent rule is used to determine where the numbering begins.
- If the compound contains more than one double bond, it is named with a diene, triene, or equivalent prefix indicating the number of double bonds, and each double bond is assigned a locator number.
