What is the general molecular formula of alkyl halides?
Options
- AC _n H _ 2n+2 X
- BC _n H _ 2n+1 X
- CC _n H _ 2n X
- DC _n H _ 2n-2 X
Correct answer
B. C _n H _ 2n+1 X
Step-by-step solution
Alkanes have the general molecular formula C _n H _ 2n+2 . Alkyl halides are formed by replacing one hydrogen atom of an alkane with a halogen atom ( X ). Removing one hydrogen atom from an alkane gives an alkyl group with the general formula C _n H _ 2n+1 . Attaching a halogen atom to the alkyl group gives the general molecular formula of alkyl halides as C _n H _ 2n+1 X . Answer: C _n H _ 2n+1 X
