What is a basic compound?
If a compound that contains an OH group also contains a metal ion, then it is a base. The formation of “free” OH groups, i.e. hydroxide ions, results in a solution that is basic. Compounds that contain “pseudo metal” cations such as ammonium ion, NH+4, bonded to an OH group are also basic.
What are 5 examples of bases?
Some common strong Arrhenius bases include:
- Potassium hydroxide (KOH)
- Sodium hydroxide (NaOH)
- Barium hydroxide (Ba(OH)2)
- Caesium hydroxide (CsOH)
- Strontium hydroxide (Sr(OH)2)
- Calcium hydroxide (Ca(OH)2)
- Lithium hydroxide (LiOH)
- Rubidium hydroxide (RbOH)
How do you know which compound is most basic?
First, scan the molecule for all non-halogen atoms with lone pairs (usually N and O). Second, imagine protonating each candidate atom and draw its conjugate acid. Third, identify the weakest conjugate acid. The protonated atom in the weakest conjugate acid is the most basic atom in the original molecule.
What is the most acidic compound?
So, compound 3 will be most acidic.
How do you rank a compound in acidity?
The order of acidity, going from left to right (with 1 being most acidic), is 2-1-4-3. The least acidic compound (second from the right) has no phenol group at all – aldehydes are not acidic.
How do you arrange compounds in order of acidity?
Arrange the following compounds in increasing order of acidity :
- P>Q>R>S.
- S>Q>R>P.
- S>R>P>Q.
- R>S>R>P.
