Why do densities of haloalkanes decrease when the size of alkyl group increases?
1 answer:
Answer:
Here's what I get.
Explanation:
Your argument makes sense. For example, the density of C₅H₁₂ is about 0.63 g/mL, and it increases gradually to a limit of about 0.83 g/mL.
With the lower alkyl halides, the halogen atom is the major contributor to the mass of the molecule. The density of chloromethane is 2.2 g/mL.
As you increase the number of C atoms, the Cl atom becomes a smaller part of the molecule. The alkyl halide becomes more like an alkane.
By the time you have reached four C atoms, the density has reached a limiting value of about 0.89 g/mL.

Answer: pH of resulting solution will be 13
Explanation:
pH is the measure of acidity or alkalinity of a solution.
Moles of ion =
Moles of ion =
For neutralization:
1 mole of ion will react with 1 mole of
ion
0.01 mol of ion will react with =
of
ion
Thus (0.012-0.01)= 0.002 moles of are left in 20 ml or 0.02 L of solution.
Thus the pH of resulting solution will be 13
