The incorrect statement regarding ethyne is

On mixing a certain alkane with chlorine and irradiating it with ultravioletlight, it forms only one monochloroalkane. This alkane could be

Of the five isomeric hexanes, the isomer which can give two monochlorinated compounds is

2 methylbutane on reacting with bromine in the presence of sunlight gives mainly

5 L of an alkane requires 25 L of oxygen for its complete combustion. If all volumes are measured at constant temperature and pressure, the alkane is :

Given below are two statements : Statement I : 2-methylbutane on oxidation with KMnO₄ gives 2-methylbutan-2-ol. Statement II : n-alkanes can be easily oxidised to corresponding alcohols with KMnO₄. Choose the correct option :

Presence of which reagent will affect the reversibility of the following reaction, and change it to a irreversible reaction : CH₄ + I₂ $$\mathrel{\mathop{\kern0pt\rightleftharpoons} \limits_{{\mathop{\rm Re}\nolimits} versible}^{hv}}$$ CH₃ $$-$$ I + HI

$$\stackrel{\bullet}{\mathrm{Cl}}+\mathrm{CH}_{4} \rightarrow \mathrm{A}+\mathrm{B}$$ A and B in the above atmospheric reaction step are :

Given below are two statements : Statement (I) : $$\mathrm{S}_{\mathrm{N}} 2$$ reactions are 'stereospecific', indicating that they result in the formation of only one stereo-isomer as the product. Statement (II) : $$\mathrm{S}_{\mathrm{N}} 1$$ reactions generally result in formation of product as racemic mixtures. In the light of the above statements, choose the correct answer from the options given below :

Butene-1 may be converted to butane by reaction with
