Answer :
Total carbons are in the structure = 13
Primary carbons are in the structure = 5
Secondary carbons are in the structure = 6
Tertiary carbons are in the structure = 1
Quaternary carbons are in the structure = 1
Explanation :
Primary carbon : It is a carbon atom that is bound to only 1 carbon atom.
Secondary carbon : It is a carbon atom that is bound to 2 carbon atom.
Tertiary carbon : It is a carbon atom that is bound to 3 carbon atom.
Quaternary carbon : It is a carbon atom that is bound to 4 carbon atom.
As we are given the name of compound is, 2,2-dimethyl-4-propyloctane.
In this compound, eight carbon are align in a straight line, two methyl group are attached at 2nd position of the carbon in main chain and a propyl group that is three membered carbon chain is attached at 4th position of the carbon in main chain.
The given compound skeletal structure is shown below.
C2H6O + 3O2 —> 2CO2 + 3H2O
Answer:
B
Explanation:
volume occupied by fixed amount of gas is directly proportional to its absolute temperature.
Answer:
V₂ = 648.53 mL
Explanation:
Given data:
Initial volume of gas = 490. mL
Initial temperature = -35°C (-35 + 273 = 238 k)
Final temperature = 42°C = (42+273 = 315 k)
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 490 mL × 315 K / 238 k
V₂ = 154350 mL.K / 238 K
V₂ = 648.53 mL
