<h2>
Answer:</h2>
Option A is correct.
<h3>Explanation:</h3>
In the options given below the isomer given in the option A of 1-tert-butyl-5-methylcyclohexane is the most stable of all. The IUPAC name for this compound is 1-tert-butyl-3-ethyl-5-methylbenzene.
Answer:
The energies of combustion (per gram) for hydrogen and methane are as follows: Methane = 82.5 kJ/g; Hydrogen = 162 kJ/g
<em>Note: The question is incomplete. The complete question is given below:</em>
To compare the energies of combustion of these fuels, the following experiment was carried out using a bomb calorimeter with a heat capacity of 11.3 kJ/℃. When a 1.00-g sample of methane gas burned with
<em>excess oxygen in the calorimeter, the temperature increased by 7.3℃. When a 1.00 g sample of hydrogen gas was burned with excess oxygen, the temperature increase was 14.3°C. Compare the energies of combustion (per gram) for hydrogen and methane.</em>
Explanation:
From the equation of the first law of thermodynamics, ΔU = Q + W
Since there is no expansion work in the bomb calorimeter, ΔU = Q
But Q = CΔT
where C is heat capacity of the bomb calorimeter = 11.3
kJ/ºC; ΔT = temperature change
For combustion of methane gas:
Q per gram = (
11.3
kJ/ºC * 7.3°C)/1.0g
Q = 83 kJ/g
For combustion of hydrogen gas:
Q per gram = (
11.3
kJ/ºC * 14.3°C)/1.0g
Q = 162 kJ/g
In pb (no3)2 there is:
Lead- 1 atom
Oxygen- 6 atoms
Nitrogen- 2
9 atoms in all
Besides nylon, HCl is formed from the reaction of adipoyl chloride and 1,6- diaminohexane , but HCl is the byproduct molecule.
<h3>What is formed when adipoyl chloride and 1,6-diaminohexane reacts with each other and what are the by products?</h3>
- Adipoyl chloride is the monomer and hexamethylinediamine is also the monomer which reacts together to form polymer.
- The polymer formed is named nylon6,6 which is a co polymer and nylon 6,6 find its use in various other activities of life.
- Nylon6,6 is a copolymer since the participation of two monomers , and not a single monomer undergoing decomposition.
- Nylon6,6 is formed with an elimination of small molecule of HCl which is considered to be a by product .
- It is formed by a condensation reaction and hence HCl is the product formed from the reaction of adipoyl chloride and 1,6- diaminohexane.
