An organic compound ' $\mathrm{A}^{\prime} \mathrm{C}_4 \mathrm{H}_8$ on treatment with $\mathrm{KMnO}_4 / \mathrm{H}^{+}$yield's compound 'B' $\mathrm{C}_3 \mathrm{H}_6 \mathrm{O}$ Compound ' $A$ ' also yields compound ' $B$ ' an ozonolysis. Compound ' $A$ ' is
1 2-methylpropene
2 1-methylcyclopropane
3 but-2-ene
4 cyclobutane
Explanation:
: Hence, the compounds ' $\mathrm{A}$ ' are 2-methylpropene and $\mathrm{B}$ is acetone.

On mixing a certain alkane with chlorine and irradiating it with ultraviolet light, it forms only one monochloroalkane. This alkane could be :
1 Propane
2 Pentane
3 Isopentane
4 Neopentane
Explanation:
: In neopentane contains all hydrogen are equivalent. So, it will give only one monochloroalkane on halogenations. The IUPAC name of neo pentane is 2, 2dimethylpropane.

2-methyl butane on reaction with bromine in the presence of sunlight gives mainly:
1 1-bromo-3-methylbutane
2 2-bromo-3-methylbutane
3 2-bromo-2-methylbutane
4 1-bromo-2-methylbutane
Explanation:
: The reactivity order of abstraction of $\mathrm{H}$ atoms towards bromine atom alkane. Bromine will be substituted to the hydrogen where carbon has least number of hydrogen atoms.
