Question

The false statement regarding alkane is (A) this does not perform polymerization reaction (B) this does not gives elimination reaction (C) it does not disappear the colour of dilute KMnO4 solution (D) it does not decolourise bromine water

Tardigrade Admin · Accepted Answer

Alkanes show elimination reactions. Higher alkanes eliminate hydrogen and lower alkanes on heating in the absence of air at

500 - 70 0^{\circ} C

.

propane C H_{3} — C H_{2} — C H_{3} 600 X^{\circ} C C H_{3} — propene C H = C H_{2} + ethene C H_{2} = C H_{2} + methane C H_{4} + H_{2}

Q. The false statement regarding alkane is

this does not perform polymerization reaction

this does not gives elimination reaction

it does not disappear the colour of dilute $K M n O_{4}$ solution

it does not decolourise bromine water

Alkanes show elimination reactions. Higher alkanes eliminate hydrogen and lower alkanes on heating in the absence of air at $500 - 70 0^{\circ} C$ .

$propane C H_{3} — C H_{2} — C H_{3} 600 X^{\circ} C C H_{3} — propene C H = C H_{2} + ethene C H_{2} = C H_{2} + methane C H_{4} + H_{2}$
