draw the organic product (if any) expected from the following reaction CH3CH2CH2OH + K2Cr2O7(aq) ---->H2SO4 is catalystNote:

m_a_m_a [10]

Answer:

The product will be propanoic acid .

Explanation:

Under the action of strong oxidizing agent that is potassium dichromate in an acidic medium primary oxidizes the primary alcohols into carboxylic acid .

$RCH_2OH+K_2Cr_2O_7\overset{H^+}\rightarrow RCOOH+H_2O$

So, when propanol is treated with potassium dichromate in an acidic medium it get converted into propanoic acid.

$CH_3-CH_2-CH_2-OH+K_2Cr_2O_7\overset{H^+}\rightarrow CH_3-CH_2-COOH+H_2O$

Determine the composition of each phase in a cu-40% ni alloy at 1300c,

Morgarella [4.7K]

To be able to answer this, you need to have a phase diagram of Cu-Ni alloy. Create a vertical line along 40% in the x-axis. Then, create a horizontal line along the temperature at 1,300°C. The intersection lies outside of the α-L boundary. Therefore, the system consist solely of the L-phase: 100% L.
