Answer:
H2O> NH3>CH4
Explanation:
Now let us look at the issue of the approximate bond angles of each specie;
H2O- 104°
NH3 - 107°
CH4 - 109°
We can see that both species are based on a tetrahedron on the basis of electron pair geometry. How ever, we must also remember that lone pairs cause more repulsion around the central metal atom atom and distort the bond angles. Thus, in the presence of lone pairs, molecules depart from the expected shape predicted by valence shell electron pair repulsion theory. Hence, the repulsion of lone pairs in water (2 lone pairs) is greater than the repulsion in ammonia (1 lone pair) and repulsion in ammonia is greater than the repulsion in methane (no lone pair).
Answer is Option-3:
<span>C</span>₆H₁₄ (Hexane)<span> and H</span>₂O are immiscible.
Explanation:
Hexane is a chain of six carbon atoms attached to each other in straight chain and hydrogen atoms. All the bonds in this compound are non-polar. Hexane molecules interact with each other through London Dispersion Forces.
While, Water molecules are polar in nature, due to electronegativity difference between Oxygen and Hydrogen atoms the Hydrogen atom is partially positive and Oxygen atom is partially negative. And water molecles interact with each other through hydrogen bonding.
Result:
As we know LIKE DISSOLVES LIKE, so both Hexane and water are different from each other, so when mixed together thay fail to develop interactions with each other, Hence immiscible in each other.
A Lewis structure is a model that uses electron-dot structures to show how electrons are arranged in molecules.
total valance electron of SeCl2 = 20
valance electon of Se= 6
valance electron of two Cl= 14
in figure shows that two bond pairs, two bond present between Se and Cl
Non bonded electron is 16
and bond pair of electron is 4
The combustion of the fatty acid called stearic acid has the the complete equation; C18H36O2(s) + 26O2(g) ------> 18CO2 (g) + 18 H2O(g)
<h3>What is combustion?</h3>
The term combustion has to do with the burning of a substance in air. For organic compounds, we get carbon dioxide and water as the products.
Thus, for the combustion of the fatty acid called stearic acid, the complete equation is; C18H36O2(s) + 26O2(g) ------> 18CO2 (g) + 18 H2O(g)
