Answer:
1-Ethyl-3-methylidenecyclopentane
Step-by-step explanation:
Formula = C₈H₁₄. An alkane has formula C₈H₁₈. ∴ X contains 2 double bonds, 2 rings, or 1 ring and 1 double bond.
X absorbs only 1 mol of hydrogen. ∴ X contains 1 ring and 1 double bond.
Hydrogenation gives 1-ethyl-3-methylcyclopentane.
Ozonolysis gives formaldehyde, so X must contain a =CH₂ group.
Hydrogenation of X converted the =CH₂ to -CH₃.
X is 1-ethyl-3-methylidenecyclopentane.
You can see the reactions in the image below.
Answer:
The percentage of amine is protonated is 63,07%
Explanation:
The reaction of an amine RNH₃ (weak base) with water is:
RNH₃ + H₂O ⇄ RNH₄⁺ + OH⁻
The kb is defined as:
As kb = 4,004x10⁻⁵ and [OH⁻] is :
1,708 = [RNH₄⁺] / [RNH₃] <em>(1)</em>
As the total amine is a 100%:
[RNH₄⁺] + [RNH₃] = 100% <em>(2)</em>
Replacing (1) in (2):
1,708 [RNH₃]+ [RNH₃] = 100%
2,708 [RNH₃] = 100%
[RNH₃] = 36,93%
Thus,
<em> [RNH₄⁺] = 63,07%</em>
The percentage of amine protonated is 63,07%
