Answer:
SN2
Explanation:
The first step of ether cleavage is the protonation of the ether since ROH is a better leaving group than RO-.
The second step of the reaction may proceed by either SN1 or SN2 mechanism depending on the structure of the ether. Methyl and primary ethers react with HI by SN2 mechanism while tertiary ethers react with HI by SN1 mechanism. Secondary ethers react with HI by a mixture of both mechanisms.
Dipentyl ether is a primary ether hence when treated with HI, the reaction with HI proceeds by SN2 mechanism as explained above.
A is true of UV rays.
B is true not of UV rays but rather of visible light.
C is true not of UV rays but rather of microwaves. (unless you actually toast your toast in a toaster like a normal person)
D is true not of UV rays but rather of radio waves.

- <em>A skeleton equation shows just the reactants and products whereas a balanced equation shows the</em><u> relative amounts of, or proportion between, reactants and products.</u>
Explanation:
The <em>skeleton equation</em> shows which <em>reactants </em>are being used and which <em>products </em>are being formed.
The reactants are shown on the left and the products are shown on the right side of the equations, separeted by an arrow.
For example, the skeleton equation to obtain water is:
From it you know that hydrogen and oxygen react to form water, yet you do not know in which ratio they do it.
Then, you balance the equation, adding the appropiate coefficients, to make the number of atoms of each kind on the reactant side equal to the number of the same kind of atoms on the product side.
This is, for the example of water, the number of hydrogen atoms on the left must equal the number of atoms of hygrogen on the right side, and the number of oxygen atoms of the left must equal the number of oxygen atoms on the right.
For the water example that is:
- 2H₂(g) + O₂(g) → 2H₂O (g)
- Showing that 2 molecuies of hydrogen (or 4 atoms) react with 1 molecule of oxygen (or 2 atoms) to produce 2 molecules of water, and that proportion (relative amounts) will always be true for that reaction.
