Answer:
kJ/mol
Explanation:
Given and known facts
Mass of Benzene grams
Mass of water grams
Standard heat capacity of water J/g∙°C
Change in temperature ΔT °C
Heat
Heat released by benzine is - 7.82 kJ
Now, we know that
grams of benzene release
kJ heat
So, g benzine releases
kJ/g
mol C6H6
Heat released
kJ/mol
Structure of a-chloro-b-methylbutyric acid (2-chloro-3-methylbutyric acid is attached below.
The structure was drawn using following information.
1) First, the parent chain was identified. The parent chain is containing four carbon atoms, also, this chain belongs to carboxylic acid as the compound name ends with Butyric acid i.e. butyr (Butane) -ic acid (carboxylic acid).
2) Secondly, the positions of substituents were assigned by using the rule which sates that the numbering in carboxylic acid must satrt from the carbonyl carbon. Therefore, the carbon which is attached to carbonyl carbon is named as alpha (2nd position) and carbon next to alpha carbon is named as beta carbon (3rd position). Hence, we add chlorine atom on 2nd carbon next to carbonyl group and methyl group at 3rd carbon with respect to carbonyl carbon.
