Answer: OPTION * 1

Explanation:

Random error caused by factor which varies from one experiment to another.

 The  product that you obtain if you evaporate the water from the NaoH layer prior  to acidifying the layer  is    salt of <u> para - tery-butyphenol</u>


<u><em>Explanation</em></u>

  • Para-tery-butyphenol    can be isolate after extracting it into NaOH solution  through  carrying out
  1.  heating  and  then cooling,
  2. then  3M  of HCl  is added to acidify.
  3. Then ice bath is done   if needed
  4. finally  the precipitate is filtered.
  • Para tery butyphenol  can be used  for production  of alkylphenolic.

Why is a phenol more acidic than a regular alcohol? Group of answer choices
Aleks [24]

Answer:

a.Phenols have the ability to spread out the negative charge that forms.

Explanation:

This happens because of  the aromatic ring the phenols have. When loosing the proton, the anion formed have different resonance isomers due to the double bonds in the aromatic ring. This resonance makes the anion more stable and prevents the reaction going backwards.

On the other hand, regular alcohol doesn't have resonace and the reaction of loosing the proton goes leftward and righward: is in equilibrium.

That equilibrium decreases the acidity of the alcohol.

What unit is used for atomic mass
kicyunya [14]

Answer:

universal mass unit

<h2 />

The universal mass unit, abbreviated u (sometimes amu for atomic mass unit), is defined as one-twelfth of the mass of the 12C atom which has been defined to be exactly 12 u. The absolute mass of a 12C atom is obtained by dividing the value 12 by the Avogadro number (NA = 6.022 137 × 1023).
