Question

How many monochlorinated products can be obtained from all the isomeric alkanes having the formula ${\mathrm{C}}_5{\mathrm{H}}_{10}$(excluding stereoisomers)?

Answer 1

Monochlorination:

• Monochlorination reaction in which there is the substitution of only one Hydrogen atom by one Chlorine atom in an organic compound.
• When ${\mathrm{C}}_5{\mathrm{H}}_{10}$ reacts with chlorine in presence of UV rays, it gives $14$ different mono chlorinated compounds (excluding stereoisomers).

${\mathrm{C}}_5{\mathrm{H}}_{10}\left(\mathrm{g}\right)\stackrel{{\mathrm{Cl}}_2}{\underset{\mathrm{uv}\mathrm{rays}}{\to }}{\mathrm{C}}_5{\mathrm{H}}_9\mathrm{Cl}\left(\mathrm{g}\right)+\mathrm{HCl}\left(\mathrm{g}\right)$

• The products are
