Question #93e1c

Answer 1

Alkanes are `C_nH_(2n+2)`
Alkyl radicals have a hydrogen ion removed and a lone electron pair remaining, `C_nH_(2n+1)`

Explanation:

An alkane is any hydrocarbon which is fully saturated with hydrogen. It has the formula

`"alkane " = C_nH_(2n+2)`

An alkyl radical is not fully saturated as it has a lone pair of electrons which makes it highly reactive. They have the general formula

`"alkyl radical " = C_nH_(2n+1)`

Alkyl radicals are formed from alkanes by the removal of a `H^+` ion, leaving the electron behind. This gives the alkyl radical a lone pair of electrons with which to do chemistry.
