One because Potassium is in the first column on the periodic table. Any element in the first column on the periodic table has one valence electron in their outer shell.
Explanation:
It shows , Hydrogen bonding , Since ,
The molecule of water have a strong electronegative atom of oxygen and a hydrogen atom ,
So , the electronegative oxygen atom can interact with the other hydrogen atom of the other water molecule .
The molecule of Carbon tetrabromide have polar bonds of carbon and bromine atom , but overall the molecule is non - polar in nature , due to its tetraderal structure , hence ,
the molecule shows only dispersion forces .
The molecule of dichloromethane has Dipole Dipole forces due to difference in electronegativity between atoms .

Explanation:
The Arrhenius acid-base theory defines an acid as a compound which when added into water increases the hydronium ion (H₃O⁺) concentration and the base as a compound which when added into water increases the hydroxide (OH⁻) ion concentration. As such, an acid-base reaction is limited to proton transfer to only OH⁻ ions forming water. Such would imply that all acid-base reactions produce water only in addition to a salt. This is not always the case as conjugate base anions for many substances can receive proton transfer.
Example: The reaction HOAc + NaCN => HCN + OAc- will occur in aqueous media because the proton (H⁺) on acetic acid (HOAc) will transfer to the cyanate ion forming hydrocyanic acid (HCN). Such occurs because the CN⁻ ion is a stronger conjugate base than the acetate ion (OAc⁻) and forms the more stable weak acid. Such is the basis of the Bronsted-Lowry Acid-Base system and states that an acid (proton donor) will transfer its ionizable hydrogen to a conjugate base (proton acceptor) if the transfer forms a weaker acid.
