Alcohols can be oxidized by chromic acid derivatives. one such reagent is pyridinium chlorochromate, (c5h5nh )(clcro3–), commonly known as pcc. draw the proposed (neutral) intermediate and the organic product in the oxidation of 1-butanol by pcc when carried out in an anhydrous solvent such as ch2cl2."

See figure attached.

Explanation:

Pyridinium chlorochromate (PCC) is a weaker oxidizing agent when compared with oth chromic acid derivatives as dichromate, for example. This results in the fact that PCC wil oxidize a primary alcohol transforming it to a aldehyde.

The entire mechanism of the reaction of 1-butanol with PCC in an anhydrous solvent is shown in the figure attached.

The neutral intermediate and the organic product (1-butanal) are both represented in the figure.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
