Carbonyl compounds can be protonated on the carbonyl oxygen. Protonation of the carbonyl oxygen gives a species whose positive c
harge is delocalized by resonance. Explain why acetic acid (ethanoic acid) is more readily protonated than acetone (propanone).

Answer:
Full explanation is given below.
Explanation:
Positive charge on carbonyl oxygen atom in protonated acetic acid is delocalized by stronger electron donating resonating effect of lone pair of oxygen atom in adjacent -OH group.
Positive charge on carbonyl oxygen atom in protonated acetone is delocalized by weaker electron donating inductive effect of two adjacent methyl groups.
Higher the delocalization of positive charge, higher will be stability of protonated species. Hence acetic acid is more rapidly protonated.
Resonance structures of protonated acetic acid has been shown below.

5.732 grams of AgCl is formed when 0.200 L of 0.200 M AGNO3 reacts with an excess of CaCl2.
Explanation:
The balanced equation:
2 AgNO3(aq) + CaCl2(aq) -----> 2 AgCl(s) + Ca(NO3)2(aq)
data given:
volume of AgNO3 = 0.2 L
molarity of AgNO3 = 0.200 M
atomic weight of AgCl= 143.32 gram/mole
from the formula, number of moles can be calculated
Molarity =
number of moles of AgNO3 = 0.04
From the reaction:
2 moles of AgNO3 reacts to form 2 moles of AgCl
0.04 moles of AgNO3 reacts to form x mole of AgCl
=
= 0.04 moles of AgCl is formed
mass of AgCl formed is calculated by multiplying number of moles with atomic mass of AgCl
mass of AgCl = 0.04 x 143.32
= 5.732 grams of AgCl is formed.
