Chemistry
1 answer:
Margarita [4]4 years ago
5 0
Looking at the elements from period three, you can identify element 2 based on element 3. It shows that element 3 is Magnesium. The ionization energy increases as it goes from left to right.

Since Element 2 has a lower ionization, just think of an atom that is to the left of Magnesium because it has a lower ionization energy. The only atom to the left of Magnesium is Sodium. So element 2 is Na, or Sodium.

The reason for using 1-propanol as the solvent of choice for recrystallization is that triphenylphosphine oxide is more soluble
tensa zangetsu [6.8K]

Answer:

True

Explanation:

Hydrogen bonding is a bond that exists between hydrogen and a highly electronegative element such as oxygen, nitrogen, fluorine etc.

The greater solubility of the triphenylphosphine oxide owes to the hydrogen bonded interaction between it and the 1-propanol.

The alkene lacks such hydrogen bonded interaction because it does not have a highly electronegative atom in its structure.

Hence, triphenylphosphine oxide is removed based on its polarity and hydrogen bonding ability.
