Explain $IUPAC$ nomenclature for halo-substituted hydrocarbons.

(N/A) The general scheme for $IUPAC$ nomenclature is: $2^{\circ} \text{ prefix} - 1^{\circ} \text{ prefix} - \text{Rootword} - 1^{\circ} \text{ suffix} - 2^{\circ} \text{ suffix}$.
For halo-substituted hydrocarbons:
$1$. $\text{Rootword} \Rightarrow$ Based on the total number of carbon atoms in the parent chain (e.g.,$Meth-, Eth-, Prop-, etc.$).
$2$. $1^{\circ} \text{ Prefix} \Rightarrow$ $Cyclo-$ (for aliphatic cyclic compounds).
$3$. $2^{\circ} \text{ Prefix} \Rightarrow$ $Halo-$ (e.g.,$Fluoro-, Chloro-, Bromo-, Iodo-$) and alkyl groups.
$4$. $1^{\circ} \text{ Suffix} \Rightarrow$ Indicates saturation or unsaturation:
$-ane$ (for $C-C$ single bonds)
$-ene$ (for $C=C$ double bonds)
$-yne$ (for $C \equiv C$ triple bonds)
$5$. $2^{\circ} \text{ Suffix} \Rightarrow$ Suffix of the most senior functional group (not applicable in simple alkyl halides).
