Which of the following is not a base? A: NH3 B. NaOH C. H3C6H5O7 D. KOH
2 answers:
Answer: Option (C) is the correct answer.
Explanation:
A base is a substance or specie that contains a lone pair of electron or a hydroxyl group, that is, OH group.
For example, , NaOH, and KOH are all bases.
But is not a base because there is no lone pair of electron and no hydroxyl group.
Thus, we can conclude that out of the given options is not a base.

Answer:
Because of its weak intermolecular forces.
Explanation:
Hello there!
In this case, according to the given description, it turns out possible for us to recall the chemical structures of both ethanol and dimethyl ether as follows:
Thus, we can see that ethanol have London dispersion forces (C-C bonds), dipole-dipole forces (C-O bonds) and also hydrogen bonds (O-H bonds) which make ethanol a liquid due to the strong hydrogen bonds. On the other hand, we can see that dimethyl ether has just London and dipole forces, which are by far weaker than hydrogen bonding, that makes it unstable when liquid and therefore it tends to vaporize quite readily.
