Answer:
2-methylebutane
Explanation:
it is a hydrocarbon and there is a specific Rule for its nomenclature.
that is known as IUPAC naming system. According to it
- The compound that has all single bonds name ends on ane.
- Names according to the number of Carbons,
* For one carbon compound it is known as methane,
* For 2 ethane,
* For 3 propane
* For 4 Butane and so on.
- select the longest chain of compound
- Start numbering with lowest substituted position at carbon
- branch compound name as Iso and neo as whole
So keeping in mind the compound can be named as
2-methylebutane
- As the longest chain contain four carbon atoms so it will name as butane
- The substitution of methyl group is on C-2
*Note: it can also named as isopantane as it is branched and have five carbons but it could not be 3-isopentane.
Answer:
a. 113 min
Explanation:
Considering the equilibrium:-
2N₂O₅ ⇔ 4NO₂ + O₂
At t = 0 125 kPa
At t = teq 125 - 2x 4x x
Thus, total pressure = 125 - 2x + 4x + x = 125 - 3x
125 - 3x = 176 kPa
x = 17 kPa
Remaining pressure of N₂O₅ = 125 - 2*17 kPa = 91 kPa
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k = min⁻¹
Initial concentration = 125 kPa
Final concentration = 91 kPa
Time = ?
Applying in the above equation, we get that:-
