To determine the skeletal formula for the given molecule [tex]$C_3BrCl$[/tex], let's analyze the options provided.
1. BrCl:
- This is an incorrect option because it does not follow the given skeletal formula [tex]$C_3BrCl$[/tex]. It contains only one bromine atom (Br) and one chlorine atom (Cl) without any carbon atoms (C).
2. [tex]$C_3H_6BrCl$[/tex]:
- This option appears more promising. By looking at the molecular formula, we have:
- 3 carbon atoms (C)
- 6 hydrogen atoms (H)
- 1 bromine atom (Br)
- 1 chlorine atom (Cl)
- This molecular formula can include the given skeletal formula [tex]$C_3BrCl$[/tex] along with the appropriate number of hydrogen atoms to satisfy the valency requirements of carbon.
3. [tex]$C_5BrCl$[/tex]:
- This option has 5 carbon atoms which does not match the skeletal formula [tex]$C_3BrCl$[/tex]. It also lacks the appropriate number of hydrogen atoms to make sense chemically, assuming typical organic chemistry conventions.
From this analysis, the correct molecular formula that fits the skeletal formula [tex]$C_3BrCl$[/tex] is [tex]$C_3H_6BrCl$[/tex].
The skeletal formula [tex]$C_3BrCl$[/tex] represents the basic framework where the placement of Br and Cl atoms is shown with three carbon atoms, and the rest of the valency is satisfied by hydrogen atoms, resulting in the molecular formula [tex]$C_3H_6BrCl$[/tex].
Therefore, the given skeletal formula [tex]$C_3BrCl$[/tex] corresponds to the molecule:
[tex]$C_3H_6BrCl$[/tex].
