Chemistry - Halogen Derivative Question with Solution | TestHub

Alkanes have the general molecular formula ${\text{C}}_n{\text{H}}_{2n+2}$.

Alkyl halides are formed by replacing one hydrogen atom of an alkane with a halogen atom ($\text{X}$).

Removing one hydrogen atom from an alkane gives an alkyl group with the general formula ${\text{C}}_n{\text{H}}_{2n+1}$.

Attaching a halogen atom to the alkyl group gives the general molecular formula of alkyl halides as ${\text{C}}_n{\text{H}}_{2n+1}\text{X}$.

Answer: ${\text{C}}_n{\text{H}}_{2n+1}\text{X}$
