Question

Which of the following is a primary alkyl halide?
A) $C{H_3}$
B) $C{H_3}Cl$
C) $C{H_2}B{r_2}$
D) None of these.

Answer 1

Hint: We have to remember that the alkyl halides additionally called haloalkane or halogenoalkanes are synthetic mixes that are frequently gotten from alkanes that contain at least one incandescent light. We can likewise say that alkyl halides are a subset of the overall class of halocarbons.

Complete step by step solution:
Now we see the Alkyl Halide classification: Alkyl Halide can be ordered based on different angles. They are as per the following.
Number of Halogen Atoms: Here, the arrangement fundamentally relies upon whether they contain one, two, or more halogen particles in their structure. Under this classification we have;
1. Mono Haloalkane: \[C{H_3} - C{H_2} - X\] [Where X can be halogens]
2. Dihaloalkane: \[X - C{H_2} - C{H_2} - X\] [Where X can be halogens]
3. Trihaloalkane: \[X - C{H_2} - CHX - C{H_2} - X\] [Where X can be halogens].
Classification based on the position of Halogen particles Along the Chain of Carbon Atoms.
The grouping relies upon how the halogen molecule is situated on the chain of carbon particles.
-Primary alkyl halide.
-Secondary alkyl halide.
-Tertiary alkyl halide.
Primary Alkyl Halide: In this sort of haloalkane, the carbon which is clung to the halogen family will be simply connected to one other alkyl gathering. It doesn't make a difference how much massive gathering is appended to it.
Thus methyl chloride $C{H_3}Cl$ is a primary halide.
Therefore, the option (B) is correct.

Note: Alkyl halides are drab when they exist in unadulterated structure. Be that as it may, bromides and iodides create shading when presented to light. Numerous unstable halogen mixes have a sweet smell.
Methyl chloride, methyl bromide, ethyl chloride and some chlorofluoromethanes are gas at room temperature. Higher individuals are fluids or solids.
The density increases with an expansion in the quantity of carbon molecules, halogen iotas and nuclear mass of halogen particles.
The haloalkanes are less solvent in water.
