The absorbed and perceived color of the solution at wavelength 533 nm will be GREEN AND YELLOW. The spectrophotometer is an analyzing machine that uses the interaction between the radiation from the visible of part of the electromagnetic spectrum and the behavior of chemical species to identify compounds. When all the wavelength in the visible light is present, we see the color of the light as white but when a wavelength is removed or absorbed, the white color will change to another color. This is the principle on which the spectrophotometer work. Thus, when the wavelength of 533 nm is removed, the color that will be perceive is green and yellow.<span />
Alkynes are reduced completely in presence of to produce alkanes.
Hydrogenation in presence of Pt is a simple nucleophilic addition process where molecule adds onto an unsaturated bond.
Hept-1-yne, hept-2-yne and hept-3-yne are constitutionally isomeric to each other. Hence, after complete reduction, all three alkynes produced heptane as only product.
So, only one seven carbon hydrocarbon was produced.
Coefficients are used here to balance the number of elements in the products and reactants. Coefficients are numbers that are placed in front of a chemical formulas in an equation. Hope it's useful.
