Solution

Ethanol
Ethanoic acid
Ethylene glycol
Oxalic acid

Solution

The addition of HBr is easiest with :

(CH₃)₂C = CH₂
CH₃ - CH = CH₂
ClCH =CHCl
CH₂ = CH -Cl

Solution

The compound most likely to decolourise a solution of alkaline KMnO₄ is :

CH₃CH = CHCH₂CH₂CH₃
C₁₀H₂₂
CH₃ - CH₃
(CH₃)₄C

Solution

Only alkenes and alkynes (or compounds having C = C or C ≡C) decolourise alkaline KMnO₄ solution.Only (a) is alkene, other three are alkanes.

Acid catalyzed hydration of alkenes except ethene leads to the formation of

mixture of secondary and tertiary alcohols
mixture of primary and secondary alcohols
secondary or tertiary alcohol
primary alcohol

Solution

benzaldehyde
toluic acid
phenyl acetic acid
benzoic acid

Solution

Butene-1 may be converted to butane by reaction with

Sn – HCl
Zn – Hg
Pd/H₂
Zn – HCl

Solution

Alkenes combine with hydrogen under pressure and in presence of a catalyst (Ni, Pt or Pd) and form alkanes.

CH₃CHO + CO₂
CH₃COCH₃
CH₃COCH₃ + CH₃COOH
CH₃COCH₃ + CH₃CHO

Solution

Aromatisation of n-heptane by passing over (Al₂O₃ + Cr₂O₃)catalyst at 773 K gives:

benzene
toluene
mixture of both
heptylene
