KMnO4 has the incorrect set of oxidation numbers. Whenever there is an alkali metal, it has an oxidation number of +1. As you can see, K is said to have an oxidation number of +2, so it is incorrect.
Answer:
<em>The pKa is 13.0.</em>
Explanation:
pKa + pKb = 14
Given, Kb of trimethylamine = 6.3 ×
pKb = - log (6.3 × )
= 1.0
⇒ pKa = 14 - pKb = 14 - 1.0
<u>pKa = 13.0</u>
<em><u></u></em>
<em>Check: For most weak acids, pKa ranges from 2 to 13.</em>
Answer:
alkene
Explanation:
Since the end only has CH2 it would be an alkene.
Alkene means their is a double bond present.
Carbon always wants 4 bonds (4-2=2) Therefore this shows us that it is a double bond, known as an alkene.
Also,
alcohol = OH
alkane = single bond
alkene = double bond
alkyne = triple bond
