Write the concentrated sulphuric acid H2C2O42H2O=2H2O+CO2+CO
masha68 [24]

Answer:

H2C2O4.2H20 → CO2 + CO + H2O

Explanation:

Oxalic acid crystals are nothing but dehydrated oxalic acid (H2C2O4 . 2H2O).

On heating, the water of crystallization is lost first. Then, the dehydrated oxalic acid decomposes into carbon dioxide(CO2), carbon monoxide(CO) and water(H2O).

Equations involved :

H2C2O4 . 2H2O → H2C2O4 + 2H2O

H2C2O4 → CO2 + HCOOH (FORMIC ACID)

HCOOH → CO + H2O

Overall equation : H2C2O4.2H20 → CO2 + CO + H2O

Give the product expected when the following alcohol reacts with pyridinium chlorochromate (PCC). (Assume that PCC is present in
Hoochie [10]

Answer:

Kindly check the explanation section.

Explanation:

Based on the description of the reacting -OH group containing Compound, the drawing of the chemical compound is given in the attached picture.

So, without mincing words let's dive straight into the solution to the question.

The reaction between the OH containing compound and PCC is an oxidation reaction.

Looking at the carbon number 1 which the first OH group and CH3 are attached to. Oxidation can not occur here as tertiary alcohol can not be oxidize.

Hence, the second OH will be oxidized into a carbonyl group, C = O. Kindly note that when alcohol oxidizes it turns into an aldehyde.

The equation for the reaction is also given the the attached picture.
